Associative, Communctative, Identity, Inverse, Distributive

[Volsdoll82]

Which property is each of the expression? Am I right on these two?

The options are Communctative, Associative, Identity, Inverse and Distributive Properties

1: ( 5 . 7) . 4 = 5 . (7 . 4)

I chose associative


2: 2 + (-2) = 0

I chose inverse and identity both

Thanks

Hi Vols Doll:

Exercise 1 is correct.

Exercise 2 is an example of the Additive Inverse property, not the Additive Identity property.

The Additive Identity property states that adding zero to a number does not change its value.

2 + 0 = 2
