Easy steps for Squaring 2 digit numbers ending with a 5:
Example: Squaring 75 i.e. (75 x 75)
1) Take the tens digit of the number, (7 in this case) and add 1 to it. (7+1=8)
2) Now multiply the original tens digit with this new number. ( 7x8=56)
3) Now take the result so obtained (56) and place 25 after it. (5625)
4) The result obtained is your answer. (Thus, the square of 75 is 5625.)
Try this with other two digit numbers ending with 5
