Question

Simplify, showing your steps. Tell the property you used in each step.
1•(-n + n)

Answer 1

1.(-n+n)
first we take bracket
u will see that they are additive inverse of each other so they are cancelled out
now u r remained with
1.(0)
u know a x 0 = 0.
it means any number multiplied with zero is zero.
so 1.(0)=0.
Thus ur final answer is \[ZERO.\]

Answer 2

so only 2 properties.\[(1.) Additive Inverse.\]\[(2.) a \times0=0.\]

Answer 3

are used*
