So we're being asked to just put in one set of parentheses into dicks expression. So that way it's valuable equal to 40. So if I'm looking at my expression, what I think the answer is going to be is if I put my Prem facie right here before the three squared and after the four. Well, let's check. So according to the order of operations, we have to evaluate the grouping Simple first and inside the grouping. Simple. We have, ah, subtraction and an expert. So you have to do the exponents first, while three squared is equal tonight. So we would have four times and I'm minus four times two. Well, no, we would have to do nine minus for which is five. So it would be left with four times five times two. And now we can do our order of operations from left or a multiplication. Excuse me from left to right. So four times five is 20 and 20 times two is 40. So now we've found where we could play set of parentheses and the value of this expression will equal to 40
