Step-by-step solution

We solve the exercise according to the order of operations.

We place the addition and subtraction exercises in parentheses in the following way to make it easier to solve:

(2+6)−10+(30−2)= (2+6)-10+(30-2)=

We solve the exercises in parentheses:

8−10+28= 8-10+28=

We place the subtraction exercise in parentheses:

(8−10)+28= (8-10)+28=
