  1. Do the multiplication before the addition. Took me a minute (maybe longer) to remember back as far as primary school. Only been ___ years! Have a wonderful holiday everyone.

Your answer to your equation is correct, however there are no parentheses in Nick’s equation. Pay attention to the mathematical order of operations.

Which would be multiplication addition subtraction.
7 plus (addition) 3 multiplied (before addition) 2 equals 13.
I’m pretty sure even without parenthesis you still go with that order.
