Vedic Mathematics is a very powerful tool for us to get quick calculations
For Multiplication of two 2-digited numbers, we can follow FOIL technique.
If you want to multiply 74×36(let's present it as ab×cd)
Find 7×3×100=2100 (a×c×100)----------multiply First to first digits-----F
Find (4×3+ 7×6)×10=540 [(bc+ad)×10]----------multiply outside and inside digits and multiply their sum with 10-----OI
Find 4×6=24 ( b×d) -------multiply last to last----------L
Add all 2100 + 540 + 24 ____________ 2664
That's the product.
