Associative Property of Addition

Tyler from tarveracademy.com explains the associative property of addition, comparing it to the commutative property and associative property of multiplication. He demonstrates that numbers can be added in any order to achieve the same result, using an example with numbers 2, 7, and 3. The video emphasizes understanding these properties for solving equations, even if they are not frequently used in proofs.

Why is it not necessary to use proofs for the associative property of addition anymore?

What is the result of adding 2, 7, and 3 in different orders?
