Question 16538: The question is to simplify:
2(7--4) + 5(2-5) divided by (-4)(6-2) This is in fraction form.
I keep coming up with the solution - 7/16, but the Universal Simplifier arrives at 37!
Here's how I arrived at -7/16:
2(11) + 5 (-3) or 22+-15 = 7
-4(4) = 16
so solution is -7/16
Please help me to understand what I am doing incorrectly, I will forever be indebted to whomever answers this!
