Answer:
-2.5, or -2 1/2
Explanation:
This one is much easier than it looks...Let's take each part of the equation step-by-step:
(-1): Parenthesis are not needed here, so we can simplify it to just -1
+(-1 1/2): This one looks tricky but remember that a positive and negative equals a negative, so this can be simplified to -1 1/2, or -1.5
Let's put these together now!
-1-1.5 = -2.5, or -2 1/2
