addition.
In this particular equation, we start with the number 6 and subtract the negative number -7.
When we subtract a negative number, it is equivalent to adding the positive version of that number.
So, -7 becomes +7 when we subtract it.
Therefore, the equation becomes:
6 + 7 = 13.
So, subtracting a negative ultimately changes the operation to addition.
The problem:
6 − (− 7) = 13
is an example where we see that subtracting a negative changes the operation to
