1. ## Inverse Operations

Hey...I need help with Inverse Operations.
Complete each equation with the missing operation.
samples:
a + 4 ? 4 = a

z - 7 ? 7 = z

2b ? 2 = b

-15b ? (-15) = b

thank you :]

samples:
a + 4 ? 4 = a what is the inverse operation to addition?

z - 7 ? 7 = z what is the inverse operation to subtraction?

2b ? 2 = b what is the inverse operation to multiplication?

-15b ? (-15) = b what is the inverse operation to multiplication?
.

3. I don't get it =/

samples:
a + 4 ? 4 = a <======= a + 4 - 4 = a (additive inverse)

z - 7 ? 7 = z <======= z - 7 + 7 = z (additive inverse)

2b ? 2 = b <======= 2b times 1/2 = b (multiplicative inverse)

-15b ? (-15) = b <===== -15b times -1/15 = b (multiplicative inverse)

thank you :]
