           Today we're gonna take a look at a shortcut for getting the square of any number which ends with the number 5.

Example: 952=?

Solution:  First consider the 52 which is 25.  Then you should multiply the 9 by the next number of 9 which is 10. You'll get 9*10=90. Now, combine both, we'll get 9025. This will be your answer. Remember this rule is applicable only to the number which ends with 5.


Problems to solve

1.    552=?

 2.   752=?

 3.   1052=?

 4.   2852=?
