Here is a Short cut for finding the square for the numbers near 10's 100's 1000's
Eg :
square of 98
98 *98 = 9604
short cut : to find square of 98
98
- 2
-----------
96
the for square multiply 2 with 2 gives 04 so suffix that value to 96 that gives 9604
* for 94
94
- 6 ( the number to get nearest value 100 -6 =94)
------
88 then suffix 36( which we got from 6* 6) = so answer is 8832
* cube of 998
998
- 2
-----------
996 ( then suffix 004 = 2*2 three digit is done cos its a three digit number)
answer 996004
