Question

1. Which property is demonstrated by this equation?
(1 + 2) + 3 = 1 + (2 + 3)

Commutative Property
Associative Property
Distributive Property

Answer 1

Associative property.....You are changing the grouping .....associating with the other numbers

idk how to explain it lol....I tried :)

Answer 2

you can think of you're re-associating the terms (ie you're making 2 associate or be grouped with 3 when you move the parenthesis around)

that's how I see it
