Multiply signed numbers
Problem
Find the value of \((-6)(4)\).
Big Picture
What this problem is really about
Handle sign and magnitude as two separate decisions. The factors have different signs, so the product must be negative; then multiply their absolute values to determine its size. Repeated addition of four copies of the negative factor provides a useful check on both the multiplication and the resulting sign.
