Hi
The way I do it is
"5 per cent of 330"
translates to 5 divided by 100 times 330
So "per" means divide and "of" means multiply

The procedure:
330*(1+5%)=
330*(1-5%)=

+5/100*330
and
-5/100*330 and then solve for the answer

forget the +- and calculate 5% of 330
330 * 5 / 100
33 * 5 / 10
33 * 1 / 2
16.5
Now as I understand the answer will be +-16.5
as it means a deviation of 5%, used in some calculation, to control the flow of 5 % positive or negative.
