# Math Help - Annoying Problem

1. ## Annoying Problem

5+8+7x0-
12-9+4+11-
(3+5)= ?

2. Have you herd of BODMAS?

Order of Operations - BODMAS

3. 5+8+7*0-12-9+4+11-(3+5)
13+0-3+15-3-5
13-3+7
10+7
17=x

I don't agree

$5+8+7\times 0-12-9+4+11-(3+5)$

$=5+8+7\times 0-12-9+4+11-8$

$=5+8+0-12-9+4+11-8$

Now we can work left to right.

$=13-12-9+4+11-8$

$=1-9+4+11-8$

$=-8+4+11-8$

$=-4+11-8$

$=7-8$

$=-1$

13 + 0 - 21 + 15 - 3 - 5 = -1

-12-9 = -21, not -3
