Speed Maths - Faster Addition

GLIMPSES ON VEDIC MATHS

I always wonder about my Grandma who does all her addition, subtraction, multiplications, divisions, interest calculations etc, mentally faster than a calculator.

I was taught of tables and complex multiplications in schools but not how to ease them to do faster calculations.
