Subtract By Crossing Digits Less Than 8
Subtraction By Crossing Digits Less Than 8
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
5 - 2 = ?
In the figure below we have 5 balloons as the first digit is 5. there is a cross on the 2 balloons as the second digit is 2
Now there is 3 balloons which does not have a cross.
So the answer is 3
5 - 2 = 3
Similarly
let us perform the following subtraction
7 - 7 = ?
In the figure below we have 7 balloons as the first digit is 7. there is a cross on the 7 balloons as the second digit is also 7
Now there is 0 balloons which does not have a cross.
So the answer is 0
7 - 7 = 0
