Question

310 - 20 / 2 x 5 + 13

I got 321 but I don't think it is correct.
Please help and show work!!

Answer 1

310-20= 290

2*5+13

2*5=10+13= 23

so it would be 290/23 which is 12.6086956522

But if there are any parenthesis between 20/2 then it would be

310-(20/2)*5+13

20/2=10

10*5=50

50+13=63

310-63=247 (: Hoped this helps (:

Answer 2

Assuming that it's written as 310 - (20/2) x 5 + 13, then this is how you should work it out:

310 - (20/2) x 5 + 13

310 - 5 x 5 + 13

310 - 25 + 13

285 + 13

298

298 should be your final answer if you're using PEMDAS.

Hope this helps!
