Subtraction of whole numbers with addition in parentheses refers to a situation where we must perform the mathematical operation of subtraction on the sum of some terms that are in parentheses.
In this case, we must remember that the subtraction will be performed on each and every term separately.
The rule is as follows:
![a - (b +c) = a - b - c](/_ipx/f_png,s_500x509/https://cdn.tutorela.com/images/a_-_b_c__a_-_b_-_c.width-500.png)
Each of the terms has its own numerical value.
