Let's see.
Let's start with the parentheses.
1-15=-14
The equation is now: 13-2(-14)/4
Now multiply -2 by -14
-2*-14=28
The equation is now 13+28/4
divide by 4
the equation is now 13+7
add
13+7=20
So the equation simplifies to 20.
Can you please tell me what order you did your operations in? I would love to know, thanks!
well @rarinstraw1195
first I disributed the -2(1-15)
then I got 13-2+30/4
next I divided 30/4
and I got 13-2+7.5
then I added -2+7.5
and I got 5.5
and last I added 13+5.5
and my final answer was 18.5
All i'd say is remember to do PEMDAS
Parentheses
Exponents
Multiplication/Division
Addition/Subtraction
Also when you distributed the -2, you forgot that it is no longer used in the equation. Shown here --->

Another thing, the parentheses were 1-15, and when -2 is distributed, it should have been -2+30 which is 28.
