(4 + 18) / (2 - 5) = −7.33 to two decimal points
Using the 'Order of Operation rules' (see below) the bracketed + and - is done first, then the division to give -7.33 as the answer.

3 divided by 4 plus 1 divided by 2 minus 2 divided by 3
5 + (2 x 7) - (18/5) = 15.4
(18/3) + 6 -(2 x 4) = 4
There is no need to simplify this, it is only a sum. 21 + (10/2) - 18 = 8
