#ProblemCorrect AnswerYour Answer
1- 9 - 1 =
Solution
Subtracting is the same as adding a negative.
- 9 - 1 → - 9 + - 1

With two numbers being added, we can apply the commutative property.
- 9 + - 1 → - 1 + - 9
Now simplify into - 1 - 9

#ProblemCorrect AnswerYour Answer
24 - 3 =
Solution
Subtracting is the same as adding a negative.
4 - 3 → 4 + - 3

With two numbers being added, we can apply the commutative property.
4 + - 3 → - 3 + 4
