VEDIC MATHS :Multiplication Easier

Here are some tricks to make multipliacation easier .
Every one will be comfortable when they multiply with a single digit numbers and similarly with division.
So we can use the following technique to make your multiplication simpler.

Multiply by 5 -you can just add a zero at the end of the number and divide it by 2.
156 x 5 --------> 1560/2 -------- > 780
Multiply by 25 –you can add two zeros at end and divide it by 4.
156 x 25 ------------> 15600/4 ---------> 3900
Multiply by 75 – You can multiply by 300 and divide by 4.
156 x 75 ------------->156x300/4 ----------->46800 /4 -------->11700
Similarly
Multiplying with 45 = number x90/2
Multiplying with 125= number x500/4
Multiplying with 225= number x900/4
Multiplying with 275= number x1100/4
