54 + 6 + 2(8 - 3 x 4)
We must do inside the parentheses first. In the parentheses, there are a
subtraction and a multiplication. We must do the multiplication 3 × 4
first, replace it by 12, and copy everything else over:
54 + 6 + 2(8 - 12)
We must do inside the parentheses first. In the parentheses, there is only
a subtraction. We do the subtraction 8 - 12, replace it by -4, and copy
everything else over:
54 + 6 + 2(-4)
There is nothing to do inside the parentheses, so we look left to right for
a multiplication or division. There is only a multiplication. We do the
multiplication 2(-4), replace it by -8, which must go inside parentheses to
keep two signs from coming together, and copy everything else over:
54 + 6 + (-8)
We do additions left to right, so we do 54 + 6 and replace it by 60 and copy
everything else over:
60 + (-8)
That's just
52
