Math Tricks

Example : 46 * 15

Step 1 : Multiply the number by 10 first i.e. : 10 * 46 = 460

Step 2 : Then talk half of that i.e. 460/2 = 230

Step 3 : Add the two i.e.  460 + 230 = 690

Step 4 : 690.(It’s the final answer)

 

Example : 164 + 166

Step 1 : Middle of the two numbers is 165 

Step 2 : Double the middle number i.e. 2 * 165 = 330

Step 3 : 330.(It’s the final answer)

174 + 176

134 + 136

 

 

 

Example 1 : 111*111 = 12321

Step 1 : Count of digits in 111 = 3

Step 2 : Starting from 1 write up to the count then back to 1 i.e. = 12321

Step 3 : 12321 (It’s the final answer)

 

Please try :

1111

11111

 

Example : 13 * 16

Step I : Sum of first number and last digit of second number or, last digit of first number and second number.

Step 2 : Answer of Step I x 10

Step 3 : Multiply last digit of both the numbers.

Step 4 : Add the solutions of Step 2 and Step 3.

Therefore, 13  x  16  = 208 (It’s the final answer).

 

Please Try :

15*14

17*15

 

Example : 352 * 11

Step 1 : Split 352 apart, i.e. : 3__5__2

Step 2 : Insert the sum of digits at the blank positions i.e. 3–(3+5)–(5+2)–2 = 3872

Step 4 : 3872.(It’s the final answer)
