What does it mean to place inclusion symbols to make an equation true?

I'm confused and I'm searching for it on Google and it didn't bring up any good clear results.





In my math workbook, it says to place inclusion symbols to make each equation true.





Example: 27+5x8-6=37What does it mean to place inclusion symbols to make an equation true?
It means this: 27 + [5 X (8 - 6)] = 27 + [5 X 2] = 27 + 10 = 37.
