25*25=625
easy method is to multiply 5 in 25 with 5 in another 25 = 25 now keep it at a side
instead of 2 in 25 write it's next coming number as here for 2 it is 3 now multiply
with another 2 in 25 you will get 6 so now keep the 6 before 25 you will get 625
it is very simpler process than multiplying
you can get results of numbers like 15,35,45,55,65,75,85,95,05.
if you can't understand you can me by your comments.
