Let me help you!
Step-by-step explanation:
Picture 1:Identity Property of Addition:
c + 0 = c0 + b = bAssociative Property of Addition:
(a + b) + c = a + (b + c)Commutative Property of Addition:
d + e = e + db + c = c + bA trick for the different properties:
- Identity property always has zero in it as a factor
- Associative Property always has parenthesis
- Commutative Property is always the same factor rearranged
Picture 2:0 = a × 0 > Zero property
b × c = c × b > Commutative Property
(a × b) × c = a × (b × c) > Associative Property
I hope this helps!
