Answer:
1, 4, 2, 3, 6, 5
Explanation:
[- 9 + 0 = - 9] is 1. The identity property of addition rule.
[(- 9)(0) = (0)(- 9)] is 4. The commutative property of multiplication rule.
[(- 9)(1) = - 9] is 2. The identity property of multiplication rule.
[- 1( 4 . 9) = (- 1 . 4) 9] is 3. The associative property of multiplication rule.
[- 9 + 1 = 1 + (- 9)] is 6. The commutative property of performing addition rule.
[- 1 + (4 + 9) = (- 1 + 4) + 9] is 5. The associative property of addition rule. (Answer)
