I am making a small change in yesterday's asking section. Today onwards all the day I will give you a simple math trick.
Today's trick
Estimation Method
I will explain it with an example.
988 + 880
First Case
First step: Round both the numbers to nearest number ending with 0.
988 - 1000 & 880 - 900
Second step: Add the rounded numbers .
1000 + 900 = 1900
Second Case
Third step: Now subtract the actual numbers from rounded numbers.
1000-988 = 12 & 900-880 = 12
Fourth step: Add the subtracted numbers got from the actual numbers & rounded numbers.
12 + 20 = 32
Last step : Now the subtract the number got in the fourth step from the number got in second step.
1900 - 32 = 1868.
The end.
I hope you like today's math trick. To view the following tricks, please follow me.
