Multiply by the formula EkanyunenaPurvena -

214 x 999

Method:

There are two sides of a product.

Left Hand Side = Multiplicand – 1

Right Hand Side = Multiplier – Left Hand Side

So, Multiplicand × Multiplier = Multiplicand – 1/ Multiplier – Left Hand Side

214 - 1 = 213

999 - 213 = 786

Ans: 213786
