INTRODUCTION

Today, Mathematics has become the global tool for technological advancement. But until today, to learn mathematics it was still necessary to learn the complex multiplication through memorization process especially in Africa.

One has to memorize the multiplication table in order to know the product of numbers from the basic numerals 1 to 12. SamKanDan MATHEMATICS COMMUNITY is a new mathematics institution based in Ghana.

SamKanDan-SKD Innusah Samuel has designed a practical approach in teaching and learning Mathematics aimed at assisting teachers driving the best possible ways to make the lesson much simpler and friendly to the students.

Mathematics which has become a "no-go-area" for many a Ghanaian child could now be studied through the simple but scientific methods in a more flexible and relaxed atmosphere without a slightest knowledge of the learner that he or she is learning something new.

With SamKanDan-SKD, you do not need to learn multiplication through memorization process any more. All you need to do is to study the simple basic multiplication rules and patterns. That is all.

You will be able to determine products of numbers such as 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, etc. SamKanDan-SKD has designed this in order to eradicate the fear of mathematics.

Multiples of 2
Multiples of 2

Rules:

Double the multiplier or simply add the multiplier to itself.

Example:

2 X 1; Double of 1 is 2. 2 x 1 = 2

2 x 6; Double of 6 is 12. 2 x 6 = 12

2 x 19; Double of 19 is 38. 2 x 19 = 38

Multiples of 3
3 times even number

Rules:

a. Write half of the multiplier and put 0 at the end. b. Double the multiplier and subtract it from Rule (a).

Examples:

3 x 2; Half of 2 is 1. Put 0 at the end to form 10. Take away twice the multiplier. Twice of 2 is 4. 10-4 = 6. Therefore 3 x 2 = 6.

3 x 4; Half of 4 is 2. Put 0 at the end to form 20. Take away twice the multiplier. Twice of 4 is 8. 20-8 = 12. Therefore 3 x 4 = 20.

3 x 12; Half of 12 is 6. Put 0 at the end to form 60. Take away twice the multiplier. Twice of 12 is 24. 60-24 = 36. Therefore 3 x 12 = 36.

 3 time odd number

Rules:

a. Write half of the multiplier (odd number by 2 you get decimal) b. Ignore the decimal point and write the number down. c. Double the multiplier and subtract it from Rule (b).

Examples:

3 x 1; Half of 1 is 0.5. Ignore the decimal decimal point to get 5. Double of 1 is 2. 5 - 2 = 3. Therefore 3 x 1 = 3.

3 x 7; Half of 3 is 3.5. Ignore the decimal decimal point to form 35. Double of 7 is 14. 35 - 14 = 21. Therefore 3 x 7 = 21

3 x 19; Half of 19 is 9.5. Ignore the decimal point to form 95. Double of 19 is 38. 95 - 38 = 57. Therefore 3 x 19 = 57.

4 times even number
4 times even number

Rules:

a. Write half the even number and put 0 at the end. b. Subtract the same even number from the answer at (a).

Examples:

4 x 2; Half of 2 is 1. Put 0 at the end to form10. Subtract the 2 from the 10. That is 10 - 2 = 8. Hence 4 x 2 = 8

4 x 4; Half of 4 is 2. Put 0 at the end to form 20. Subtract the 4 from the 20. That is 20 - 4 = 16. Hence 4 x 4 = 16.

4 x 12; Half of 12 is 6. Put 0 at the end to form 60. Subtract the 12 from the 60. That is 60 - 12 = 48. Hence 4 x 12 = 48.

4 times odd number

Rules:

a. Write half of the odd multiplier down. b. Reject the decimal point to get a whole number. c. Subtract the odd multiplier from the answer at (b).

Examples:

4 x 1; Half of 1 is 0.5. Reject the decimal point to get 5. Subtract the 1 from the 5. That is 5 - 1 = 4. Hence 4 x 1 = 4.

4 x 3; Half of 3 is 1.5. Reject the decimal point to get 15. Subtract the 3 from the 25. That is 15 - 3 = 12. Hence 4 x 3 = 12.

4 x 13; Half of 13 1s 6.5. Reject the decimal point to get 65. Subtract the 13 from the 65. That is 65 - 13 = 52. Hence 4 x 13 = 52.
