So we're being told that this student made a mistake, so we want to find a mistake, and then we want to actually go ahead and find the correct answer.
00:08
Well, the student is being asked to evaluate the expression 5 plus 3 times the quantity of 2 minus 6.
00:14
So we can do this using the order of operations.
00:17
Well, remember, to do that, we first must evaluate our grouping symbols, which in this case would be 2 minus 6, which is negative 4, which they did.
00:26
So this first line is all set.
00:27
Well, now, if you notice our two operations left, our addition and multiplication.
00:33
Well, according to the order of operations, we should multiply three times negative four next...
