Final answer:
Four examples are given, each demonstrating how combining two negative numbers results in a negative sum.
- -5 + (-7) = -12
- -10 + (-4) = -14
- -6 + (-11) = -17
- -8 + (-15) = -23
Step-by-step explanation:
The question asks for four other equations where both sums are negative. When two negative numbers are added together, the result is also negative.
Following this rule, we can construct several equations with two negative sums. Here are four examples:
- -5 + (-7) = -12
- -10 + (-4) = -14
- -6 + (-11) = -17
- -8 + (-15) = -23
In each of these equations, both numbers being added are negative, which results in a negative sum according to the rules of addition for negative numbers.
