Answer: 0
Step-by-step explanation: According to the order of operations, or PEMDAS, we first simplify what's inside the parentheses.
So here we have 2³ ÷ 1.
Remember, 2³ is the same as 2 × 2 × 2 or 8 and 8 ÷ 1 is 8.
Now we can rewrite the problem as followed.
3 - 8 + 5
Watch out for this last step. Students who use PEMDAS often think that addition must always be done before subtraction. However, that's not necessarily the case. If subtraction appears before addition as we read the problem from left to right, we will do the subtraction first.
So here, we subtract 3 - 8 which is -5 so we have -5 + 5 which is 0.
Notice that I wrote out all the steps of this problem. When solving order of operations problems, it's very important that you write out all the steps so that you can avoid careless mistakes.
