Hi I wanted some help with this question, I don't want the answer though as I want to try to see where my workings are going wrong.

3 x 34 / 9 - 2 (10 - 6) - 4 / 2

A -13

B 5

C 6

D -14

But I'm getting -3. Here's how I work through the equation using PEMDAS as a guide to order:

3 x 45 / 9 - 2 (10-6) - 4 / 2

= 3 x 45 / 9 - 2 (4) - 4 / 2

= 135 / 9 - 2 (4) - 4 / 2

= 15 - 2(4) - 4 / 2

= 15 - 16 - 4 / 2

= 15 - 16 - 2

= -3

please can someone tell me where I'm going wrong?

on the fourth line of your solution,

2(4) = 8, not 16.

thus,

= 15 - 8 - 4/2

= 15 - 8 - 2

= 5

hope this helps~ :)
