Easy Multiplication
 

 Finding the square of a number which ends in 5

 
1. 752
which means 75*75 = 5625
 
The answer is in two parts: 56 and 25.
The last part is always 25 which is 52
The first part is the first number, 7, multiplied by the number "one more", which is 8:
So 7 x 8 = 56 
Finally the result 5625
 
 
Similarly 652
ie 65*65
 
Multiply 6 and 7 ( ie 1 more than 6)  which gives 42
52  is 25.
So the final result is 4225
 
Try by yourself
