Suppose you are adding two numbers
96 + 112 = 208
➡️ Step no 1:
♀️ First round the numbers to the nearest hundreds digit.
96 + 4= 100
➡️ Step no 2:
♀️ Now Add the result from step no.1 to the other number.
100 + 112 = 212
➡️ Step no 3:
♀️ Add or subtract the result from step no. 2 by the number you rounded off.
212 - 4 = 208
