Determine whether the two expressions are equivalent. If so, tell what property is applied 18 + (6 +20) and (18+6) + 20
O no
O yes: Identity Property
O yes; Commutative Property
O yes, Associative Property

Yes, Associative Property

Step-by-step explanation:

If you add these numbers you do in fact get the same answer. Its all addition, so we can just add them up. It comes out the same both times.

Identity property is when you add 0 and get the same number or multiply by 1 and get the same number.

This is Identity:

44 + 0=44 Identity (addition)

44 × 1 = 44 Identity (multiplication)

18+6+20=20+18+6

This is Commutative property. See how the numbers moved around. The 20 was last then it was first. Like "commuting" is driving back and forth to work, Commutative prop, you will see the numbers move back and forth and change order.

YOU HAVE ASSOCIATIVE PROPERTY. The numbers are in the same order. 18, 6, 20 and 18, 6, 20. But they are GROUPED differently. On the left the 6 and 20 are "associating" and on the right the 18 and 6 are "associating" having their exclusive little get together in the parenthesis. The order did not change just the GROUPING so this is ASSOCIATIVE property.
