how to solve the math story question

Story questions in integer chapters for students are difficult. The ability to solve the overall story question for junior high school students in Indonesia is still relatively low. This is probably because the story question questions require the ability to properly understand each given problem. the number chapter that is the basic mathematics contains many questions of story questions. And strangely when the question of the mathematics story of the number chapter given to the students the results remain disappointing.

The ability of students to do literacy math problems is necessary in the habit. With the aim that the more students are accustomed to solving story questions tailored to the problems of day-to-day, the child's ability to understand every story question.

National Examination Questions and year-end exam questions have many that use story question items. It is clear that the government especially the Ministry of Education wishes Indonesian students have higher thinking skills, not only skills in performing arithmetic operations but already directed to solve math problems

There are many different types of math story questions related to the topic of numbers. Today we will try some math story questions about numbers and how to solve them.

Example of integer story 1

The provincial OSN contest set rules for students who answered the right questions score 4, incorrectly scored (-2) and not answered (-1). Of the 50 questions given by participants P answered 43 questions and 12 of them wrong. The total score earned by P participants is ...

a. 93              c. 117

b. 100           d 124

Settlement

sum = Answered + not answered

50 = 43 + not answered, means not answered 7

Answered = B + S

43 = B + 12 then the correct question is 43-12 = 31

Total score = B x 4 + S x (-2) + T x (-1) = 31 x 4 + 12 x (-2) + 7 x (-1) = 124 - 24 - 7 = 93

The temperature in the refrigerator is -13ºC, while the temperature in the room is 32ºC. The temperature difference in both places is ....

A. 45ºC

B. 18 ºC

C. -18ºC

D. -45 ºC

completion

Temperature difference = highest temperature - lowest temperature

                           = 32ºC - (-13ºC)

                          = 45 ºC

Example of integer story 3

In the Mathematics competition, each correct answer is given a score of 3, the wrong answer is given a score of -1, and if not answered a score of 0. Of the 40 questions tested, Dedi answers 31 questions, of which 28 questions are answered correctly. Dedi's score is ....

A. 81 C. 87

B. 84 D. 93

Number of questions = Answered + not answered

40 = 31 + not answered, means not answered 9

Answered = B + S

31 = 28 + S then the question is answered incorrectly there is 31-28 = 3

Total score = B x 3 + S x (-1) + T x (0)

                = 28 x 3 + 3 x (-1) + 9 x (0) = 84 - 3 - 0 = 81

Sample integer story question 4

If the "#" sign means the number of the first five numbers and three times the second number, then (-6) # 10 is ....

  A.-60 C. 0

  B.-30 D. 30

How to solve

-6 # 10 = 5 (-6) + 3 (10) = -30 + 30 = 0

Example of integer story question 5

If a = -4, b = 3, c = -2 and d = 1, the value of

ab + bc - cd - abcd is ....

A. -44 C. -36

B. -40 D. -24

Settlement

ab + bc - cd - abcd = (-4) (3) + (3) (- 2) - (-2) (1) - (-4) (3) (- 2) (1)

                                  = -12 + -6 + 2 - 24

                                  = -40

 Example of integer story question 6

Zika is 3 years older than Yeli. While Yeli 5 years older than Fari. If their age is 49 years, then the age 

of Zika is ....

A. 12 years C. 20 years

B. 17 years old D. 22 years old

HOW TO LIST AND VERIFY ALEXA IN WEB OR BLOG

HOW TO LIST AND VERIFY ALEXA IN WEB OR BLOG

Who does not know alexa rank? Yes, the alexa rank site is a site that analyzes the ranking of 

websites from around the world. most of the webmasters use alexa rank as a benchmark of the 

success of the website that he manages. The webmasters are competing to get the top possition

of millions of sites on this world.

Alexa itself provides an assessment based on site traffic owned. The more traffic to the site, 

the ranking in alexa rank will be better. If in PA, DA or PR, the best rank is the one that 

has the greatest value, then the best ranking alexa rank is ranked which has the smallest 

value, just like the class champion. Currently the best alexa ranking is still held by 

google.com.

To get detailed information about the development of your site, of course you need to register your site or blog to alexa. Although alexa is not the only benchmark for success of a site or blog, but at least you can know the progress of your site from day to day, week to week and month to month through methods applied by alexa by registering the site or blog.

Alexa itself provides various types of packages that you can choose from basic start, insight, advanced and advanced high traffic. All the packages have different prices and features. You can try these packages for free for 7 days and then paid at a price that has been determined.

In addition to the various packages mentioned above, sebenanya alexa also provide free services (free). It's just lately, after the alexa website alteration appearance, the free service seems to disappear just like that. As a result, it is not uncommon for people to assume that the free alexa service has been removed by alexa parties. But you do not have to worry, this time I will give you the latest way to register your website or blog to alexa for free.

Here is how to list and verify website or blog in alexa for free:

How To List Free Alexa: 

1.    Log in to the following URL to be able to claim to the site or blog you have: 

     http://www.alexa.com/siteowners/claim 

2.    Enter the URL of your website or blog box provided, then click continue

      3. On the next page you will be prompted to login or register first. For those who have never signed  up in alexa, you can list with an email address or via facebook. I suggest you to choose through  facebook course, so the registration process can be more easily and quickly.

      4.    Next you will be asked to verify the site or blog with the method provided.

How to Verify Alexa on Website or Blog:

Alexa provides 3 ways or methods to verify your website or blog that you have. But of the three methods, only 2 methods you can use for free. One method available, can only be used for alexa users paid version.

The following are the two alexa rank verification methods:

1)Upload an alexa verification file to your site's root directory. This method can be considered pretty troublesome, but also can last long. This means that if you use wordpress and want to switch themes, then you no longer need to re-verify your alexa.

Here are the details of how to verify using alexa file upload method:

a. First download the alexa file provided, then upload the file into the root directory of your site. (usually the site directory is htdocks or public_html directory). To upload the file, you can use FTP Client filezilla or something else.

b. When finished uploading to your site directory, then you just click the "verify the file on your site" to continue the verification process.

2. Add an alexa verification ID to your homepage.

This method I use most often, because it is more simple and easy. I usually do alexa ID verification directly via wordpress seo plugin by yoast. In addition to verification ID via plugin, this second method can also be done by adding a meta tag on the homepage. Therefore that is usually the method is the most widely used by the owners of the blog, considering not necessarily every blog can do the verification with the first method.

            Here's how to verify alexa via alexa verification ID:

1.      For those of you self hosted wordpress users and use plugins that support alexa verification, such as wordpress seo plugin by yoast, the way of verification is to copy and paste the alexa ID given into the plugin. Then click "verify my ID"

2.      for those who do not use the plugin, you can copy the meta tag provided and please insert the meta tag under <head>. After that please click "verify my ID"

If you have verified using one of the two methods above, then the next step is to provide information or data needed for your site or blog. The trick is to click My Dashboard-> Site Management-> Edit Site Listing

Site Title: Fill in the title of your site or blog.

Site Description: Fill in with your site description.

Site Owner: Fill in the name of the site owner.

Address: The address of the site owner.

City: City site owner.

State / Province: Province site owners.

Zip Code: Fill in the zip code.

Country: The country of the site owner.

How to easily calculate the installment of the bank

Calculating the installment of bank loans or credit is included in the chapter of social arithmetic. This chapter is disliked by students because the form of the question is a story question. The difficulty of understanding the story questions is often in the natural by students. Problems are answered, social arithmetic that has a wide range include selling price, purchase price, profit, loss, percentage of profit or loss, bank interest, bank interest percentage, initial savings, final savings, long saving, installment and so on Because of its scope we discussed it one by one way of settlement. We will then work by compiling the solution of social arithmetic questions in accordance with the mindset of the students. We start how counting installments or installments.

For more details let us refer to his example.

examples of national exam questions 1

Bhima bought a bicycle worth Rp24.000.000,00 which has matured Rp15.000.000,00 and the rest will be paid in installments for 20 months. If the interest rate is charged 10% per year, then the monthly Bhima mortgage is ...

A. Rp600.500,00 C. Rp535.000,00

B. Rp575.000,00 D. Rp525.000,00

Settlement

The loan size is = 24,000,000 - 15,000,000 = 9,000,000

Loans will be paid in installments of 20 months, the principal installment = 9,000,000 / 20 = 450,000

1 year loan interest = 10% => 10/100 x 9,000,000 = 900,000 means

1 month loan interest = 900,000 / 12 = 75,000

so big installment = principal + 1 month loan interest = 450.000 + 75.000 = 525.000

sample questions about big installments

Motorcycle Loans

Budi bought a motorcycle worth Rp 18.000.000,00 with a credit system if the percentage of bank interest 10% per year. If Budi pay an advance of Rp 6.000.000,00 and the shortage will be paid in installments for 4 years. then the monthly installment amount is ....

a. Rp 530.000,00 c. Rp 430.000,00

b. Rp 450.000,00 d. Rp 350.000,00

Settlement

The loan amount is = 18,000,000 - 6,000,000 = 12,000,000

will be paid in 4 years means 4 x 12 months = 48 months

installment principal = 12,000,000 / 48 = 250,000

1 year interest = 10% => 10/100 x 12,000,000 = 1,200,000 means

flowers 1 month = 1200.000 / 12 = 100,000

so big installment = principal + interest 1 month = 250.000 +100.000 = 350.000

Not easy, in the next article, we will discuss how to determine the length of saving and the percentage of bank interest rates. Understanding this chapter will have many benefits for you. One time if you are dealing with credit services then you can already calculate yourself how many installments so it is not easy to be fooled by low-interest inducements.

So hopefully useful!

the smart solution solves the fractional HOT problem

The smart solution solves the fractional HOTS problem

Higher Order Thinking skill (HOTS) is influenced by students' habits to analyze a problem. Fractional material has a number of types of questions that fall under the HOT category. then how to make the matter that belong to this high-level thinking category can be easily understood by the students. This is what homework is for teachers.

Each teacher has his own technique in delivering the subject matter to the students including among the techniques in delivering fractional material related to the matter of HOT. the most powerful technique in solving the fractional HOT problem in my opinion is the intelligent solution technique.

The intelligent solution technique in making problem solving of mathematics about HOT uses different approach with ordinary teaching method. Here are some steps taken in smart solution techniques

1. In the intelligent solution techniques teachers are required to direct students to make a pattern of completion.

Making a mathematical problem or math problem into a certain pattern so easy to remember and apply. Teacher skills create a learning plan that directs students to make the current pattern of completion is rarely used. They usually deliver what kind of material is contained in the book. Therefore it takes an innovation and motivation by teachers in improving these skills.

2. Techniques of intelligent solutions require students to quickly respond to a problem, connecting the subject matter with other materials they are more mastered.

The weakness of the students is slowly responding to the relation of the subject matter with the other material. This is because the learning process they have been doing, every material presented is impressed new material and not as an ongoing material. For example this is the relationship of material function with the material comparison and others.

3. intelligent solution techniques require meaningful learning process to students. This means that learning by this technique convinces students that this technique is very useful to them, it will be very helpful for them. That way the child's motivation will  increase.

this time we will learn how to use this technique to solve the HOT matter of fractions that would normally be issued in the graduation exam

examples of HOT fractions 1

Pak Jono divides some money to his three children. The first child gets 2/5 parts. 

The second child gets 1/4 part and the third child receives Rp175.000,00. The amount 

of money Mr. Jono distributed to all his children is ....

A. Rp700.000,00

B. Rp500.000,00

C. Rp437.500,00

D. Rp288.750,00

how to easily solve it with smart solutions 

The third child = 1 - (2/5) - (1/4)

                                  = (20-8-5) / 20

                                  = 7/20 section

Then The amount of money distributed to all children = 20/7 x 175,000 = 500,000

examples of HOT fractions 2


Mr. Andi plans to build ceramics on the floor of his house. He offered the job to Budi 
and Candra. Budi is able to complete for 24 days. Candra is able to complete 40 days. 
If Budi and Candra will cooperate Installation of cramic on the floor of Mr. Andi's house 
can be finished in time ...
a. 8 days c. 16 Days
b. 15 days d. 32 days
 
how to easily solve it with smart solutions




if they work together
then the work will be finished in time = (24 x 40) / (24 + 40) = 960/64 = 15 days



So the article about how easy or smart solution in solving the problem of fractional HOT
Hopefully with the intelligent solution solutions we offer make your learning situation 
more meaningful by students, it becomes easy to understand and makes students more 
critical in developing patterns of mathematical patterns that form the basis of intelligent
 solution techniques.
