Subtract By Crossing
Subtraction By Crossing
Subtraction by crossing means we will put a cross on the objects equal to the second digit and the remaining objects is the answer.
Steps to perform the subtraction:
For example let us perform the following subtraction
8 - 3 = ?
In the figure below we have 8 balloons as the first digit is 8. there is a cross on the 3 balloons as the second digit is 3
Now there is 5 balloons which does not have a cross.
So the answer is 5
8 - 3 = 5
Similarly
let us perform the following subtraction
8 - 7 = ?
In the figure below we have 8 balloons as the first digit is 8. there is a cross on the 7 balloons as the second digit is also 7
Now there is 1 balloon which does not have a cross.
So the answer is 0
8 - 7 = 1
