So im given an equation with 4 variables. Each variable represents;
a=22, b=17, c=6, d=4
a+b-c-d
So that would give us;
22+17-6-4
Using PEMDAS, I know to add before I subtract
Following these rules, I come up with 35
However I am doing a test on a site called Plato, which is so I can earn my credits. Every time I do it this way it tells me i'm incorrect. Is there another way to do this so Plato doesnt keep telling me i'm wrong? Or maybe I am wrong? I need some instruction.

vocaloid · Answer

when you have adding and subtracting together, go from left to right

vocaloid · Answer

so you just do

22 + 17

then -6

then -4

PEMDAS acronym is a bit misleading

when you have multiplication and division in the same problem, you go from left to right, even if it means doing division first

same thing with addition/subtraction
