Add and subtract signed numbers and explain the meaning of the sign changes.
Subtract signed numbers
Problem
Find the difference: \(5~-~(-3)\).
Big Picture
What this problem is really about
Make the subtraction easier to interpret by rewriting it as addition of the opposite. The opposite of a negative number is positive, so the two signs affect both the operation and the second value. Evaluate the resulting positive addition, then check that subtracting a negative moved the starting value upward rather than downward.
