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 (106)  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~ :)
