In this problem, we're being asked to simplify the given expression.
00:04
To do that, we're going to use the order of operations, which tells us to evaluate our parentheses first.
00:09
So that means i would be looking within this bracket.
00:13
Well, even within this bracket, we have a set of parentheses.
00:15
So we first must do 15 minus 20.
00:19
Well, when we do 15 minus 20, that means we're starting with 15 positives, and we have to take away 20 positives.
00:26
Well, we don't have enough to do that.
00:28
Well, how many would be left over? there would be five left over that are unaccounted for.
00:33
So that means we're going to have 15 minus 20 will give us negative 5...
