Trick Math Problem

Introduction for trick math problem:

Mathematics plays an important role in all fields.  In mathematics, we can learn many chapters such as algebra, probability, number system, number theory, matrix, integral, vector, geometry, graph and so on.  Here, we are going to learn some trick for using in math problem.
Some Tricks for Math Problems – Trick Math Problem

Math trick 1

Process 1:

First, consider the numbers from 1 to 9 (1, 2, 3, 4, 5, 6, 7, 9), but not to take the number 8.

Process 2:

Then the numbers can multiply with the number that is multiplied by 9 (9, 18, 27, 36, 45, 54, 63, 72, 81).

We get the answer in 9 digits and also all digits are equal (example: 111111111)

Process 3:

Now, multiply same numbers (1 2 3 4 5 6 7 9) by 18

The answer will become also same 9 digits (example: 222222222).

12345679 x 81 = 999999999

12345679 x 72 = 888888888

12345679 x 63 = 777777777

12345679 x 54 = 666666666

12345679 x 45 = 555555555

12345679 x 36 = 444444444

12345679 x 27 = 333333333

12345679 x 18 = 222222222

12345679 x 9 = 111111111

Math trick 2

Process 1:

First take the value 6

Process 2:

Sum of the taken number 6 with 1 (6 + 1 = 7)

Process 3:

Now, multiply the two values (6 * 7 = 42)

Then, we take the two digit same number 66, add the value 1 with out taken 66 (66 + 1= 67) then multiply the two values 66 * 67 = 4422

6 x 7 = 42

66 x 67 = 4422

666 x 667 = 444222

6666 x 6667 = 44442222

66666 x 66667 = 4444422222

666666 x 666667 = 444444222222

6666666 x 6666667 = 44444442222222

66666666 x 66666667 = 4444444422222222

666666666 x 666666667 = 444444444222222222

I have recently faced lot of problem while learning degrees and radians, But thank to online resources of math which helped me to learn myself easily on net.

Trick 3 for Math Problems – Trick Math Problem

Math trick 3

Process 1:

Obtain the value 1.

Process 2:

Multiply the value 1 with same number 1 (1 x 1 = 1)

We get the result 1

Process 3:

Now, we obtain the two digit same number (that is 11) then multiply 11 with the same number 11

Now, we get the result 121

1 x 1 = 1

11 x 11 = 121

111 x 111 = 12321

1111 x 1111 = 1234321

11111 x 11111 = 123454321

111111 x 111111 = 12345654321

1111111 x 1111111 = 1234567654321

11111111 x 11111111 = 123456787654321

111111111 x 111111111 = 12345678987654321
