Question

Using Nikhilam Sutra calculate $88\times 86=$___

Answer 1

88 -12
86 -14
______
74 /168

1. Both the numbers are closer to 10 power (base 100).
2. 88 is 12 less than 100 and 86 is 14 less than 100.
3. $(-12)\times (-14)=168$ (Since base is 100, we need only 2 digits (i.e. 68), so carry forward 1)
4. 88 + (-14) OR 86 + (-12) = 74
5. Add 1(carry forward) to 74 = 75
5. Final answer = 7568
