Easy Multiplication Tricks

These are few easy multiplication tricks that will help you to do the maths mentally.

Learn this tricks it will be very handy while solving maths problems in the competitive exams. There are 3 rules you will need to learn the numbers that smaller than 10, numbers that are very near to 100 and numbers that slightly higher than 100. Off-course the technique can be used with any numbers. The rules are as follows

:

1. Multiplication trick for the numbers that are a slightly over 100

For example: Multiply 105 x 104 = 10920

Step 1: Multiply the numbers in unit place : 5 x 4 = 20 , notice the last 2 digits

Step 2.  add unit digit on one No. to another FULL number, 105 + 4 = 109, you can also do 104 + 5 = 109

2. Multiplication trick for the numbers near to 100

For example : Multiply 89 x 97

Step 1: Subtract the numbers with 1oo, in ex. we get 100-89 = 11 and 100- 97 = 3

Step 2: Multiply the results, 11 x 3 = 33, this will form the last 2 digit

Step 3: Subtract in cross for ex. either 97-11 = 86 or 89- 3  = 86, either way you will always get the same result.

Step 4. The number is 8633

3. Multiplication trick for the numbers less than 10

For example : Multiply 8  x 9

Step 1: Subtract the numbers with 10, in ex. we get 10-8= 2 and 10- 9 = 1

Step 2: Multiply the results, 2x 1 = 2 this will form the last digit

Step 3: Subtract in cross for ex. either  8 -1 = 7 or 9- 2  = 7, either way you will always get the same result.

Step 4. The number is 72
