in this problem we can follow previous rule by subtracting 101-1=100, right side -32. Now, Rhs 100-32=68, Lhs 100-1=99. Final Answer is 9968

To eliminate sign carry 1 from left to right in case of minus sign

[@lmaoded7505]

A general way of doing this where you do not need to think of carry and stuff - Subtract both numbers by nearest power of 10 individually. This will give a positive or negative number - Multiply the numbers derived in above step - Add "original" number and the "subtracted" number of other number and multiply by the power of 10 - Add the above number with the product of subtracted numbers For example, 88 * 105 Nearest power of 10 = 100 105 +5 88 -12 ------------------------ 93 | -60 Answer = 93 * 100 - 60 = 9240
