1. commutative - addition
2. inverse - addition
3. associative - multiplication
4. symmetric
5. commutative - multiplication

Answer 1

can you use some parenthesis?
is that ((8+1)/8) -1 + 5 = 5?
or
8 + (1/8) -1 + 5 = 5
you gotta use the parens so i know the order.

Answer 2

(1/8) lol sorry

Answer 3

8+(1/8)+(-1)+5=5
8 + 0.125 - 1 + 5 = 5
12.125 = 5
I don't think any statements can justify that.
Is there a "none" answer?
