What is the commutative property of addition?
What is the commutative property of addition?
- $a + b = a - b$
- $a + b = 2a$
- $a + b = a imes b$
- $a + b = b + a$ (correct)
What is the associative property of multiplication?
What is the associative property of multiplication?
- $a imes (b imes c) = (a imes b) imes c$ (correct)
- $a imes b imes c = a imes (b + c)$
- $a imes b + a imes c = a imes (b + c)$
- $a imes (b + c) = a imes b + a imes c$
What is the distributive property of multiplication over addition?
What is the distributive property of multiplication over addition?
- $a imes (b + c) = a imes b imes a imes c$
