–6(8 + 12) has "grouping symbols" which happen to be parentheses. There are "Order of Operations" rules which tell us which operations must be done first. Any work that you see inside parentheses MUST be done first. Therefore, y our first step here is to evaluate 8+12. Would you do that now, please?

Repeat: Any math operation enclosed by parentheses has to be done first. Yes, the sum is 20. Now multiply that 20 by -6. Can you explain how we know we must multiply?

because they are right next to each other with no symbol.
