(-5)(-3)-(2)(3)
--------------------
3[5/(3-8]
Let's take the top, first
(-5)(-3) - (2)(3) =
15 - 6 =
9
The bottom is a little trickier
3 [ 5 / (3 - 8) ] = work inside the parentheses, first
3 [ 5 / (-5) ] = now, inside the brackets
3 [ -1 ] = now, just multiply
-3
So.....we end up with
9 / - 3 =
-3
