Question

Which of the following shows the additive inverse property?
A. 8 + 0 = 8
B. 8 + 1 = 9
C. 8 + (-1) = 7
D. 8 + (-8) = 0

Answer 1

the additive inverse, or opposite, of a number a is the number that, when added to a, yields zero.

Answer 2

what
\[\phi\] sais

Answer 3

Ok how did you get that (:?

Answer 4

First, do you know the answer ?

Answer 5

well im guessing a? bc of what you said..Sol idk..What exactly IS additive inverse property?

Answer 6

This explains it

Answer 7

Additive inverse is just a fancy way to say a - a = 0
or given any number (call it a) there is another number (-a) that you can add to a
a+ (-a) to get zero.

Answer 8

so is it A? or not? i'm wanting to figure this out by knowing the answer and figuring out how you got it.

Answer 9

which of the answers shows 2 numbers added together that give you zero?

Answer 10

option A is an example of the "identify property of addition"
See http://www.khanacademy.org/video/identity-property-of-0?playlist=Developmental+Math+2

Answer 11

Well D does and that's pretty much it

Answer 12

Yes, and notice that one of the numbers is 8 and the other is -8
so 8 and -8 are additive inverses.
It is a definition, so you have to memorize it.

Answer 13

Watch Khan's video's if this is confusing, it will help it all sink in.

Answer 14

ok now..let's go to the next one and ill see if im right
