Write the property that best matches the
following:
a.) 13 + -13 = 0
b.) (-12) + 16 = 16+ (-12)

Step-by-step explanation:

Property for Addition:

a + b = b + a - commutative

(a + b) + c = a + (b + c) - associative

a + (-a) = 0 - inverse

a + 0 = a - identity

We have:

a) 13 + (-13) = 0 → inverse property

b) (-12) + 16 = 16 + (-12) - commutative property

these are pretty self explanatory if you know what supp right and com angles are
