We've already discussed some
short cut tips for Multiplications. You can check that post
Here. Now we shall discuss another Simple and Useful method for Multiplication. In this method we take a base (according to the given numbers) and do the multiplication according to that base. Assume that you have to multiply 97 with 92. The power of 10 to which these two numbers are close is 100. We call this 100 as the
base. Now write these two numbers with the difference from the base.
97 ------> -3 (because 97 is obtained as 100 - 3)
92 ------> -8 (because 92 is obtained as 100 -8)
