Step-by-step explanation: The order of operations gives us instructions on how to simplify expressions that contain more than one operation.
In this problem, we have both addition and multiplication.
According to order of operations, we must do the multiplication before the addition.
So here, our first step is to multiply 2 × 4 which is 8 and we have 2 + 8 which is 10.
Notice that if we had added first then multiplied, we would have had 2 + 2 which is 4 and 4 × 4 is 16 which is an incorrect answer.
You can see that order of operations is very important.
