algebra equations i don't get!!!?

Question

1. In the expression a x b, the expressions a and b are called_____.
2. The _____ _____ states that a x (b + c) = a x b + a x c.
3. The additive inverse of a, -a is also called the _____ of a. The multiplicative inverse of a, 1/a, is also the _____ of a.
True or False
4. the absolute number of a number is alwyas positive.
5. Addition and multiplication are communitive.
6. We call 0 the additive identity and we call 1 the muliplicative identity.
QUESTION
7. What is the additive inverse of 0?

Answer 1

1, multiplicands
2. distributive law
3. negative, reciprocal
4. false. The absolute value of 0 is not positive.
5. True
6. True
7. 0

Answer 2

Yusuf's answers are sophomoric, and shame on the voter who gave him a thumbs up.

1. The question is not clear. They may be called factors, or constants, or literal quabtities. You will have to consult your text, and find the context they are assuming.

2. Distributive Law (NOTE: The two blanks are significant.)

3. opposite, reciprocal.

4. False. Abs(0) = 0 is not positive.

5. True. This means a + b = b + a and a*b = b*a.

6. True.

7. Zero. The additive inverse of x is a number y such that x + y = 0. The additive inverse of 0 is y such that 0 + y = 0. Clearly the answer is 0. {NOTE: We usually say the additive inverse of x is -x. Thus, the additive inverse of 0 is -0 which is 0.]

Answer 3

1. parameters
2. distributive
3. negation, inversion
4. true
5. true
6. true
7. since 0 is additive identity, so it doesn't have additive inverse
