Question

What is the opposite of the opposite of 8 1/2?
A. +(+ 8 1/2)
B. - (- 8 1/2)
C. +(- 8 1/2)
D. -(+ 8 1/2)

Answer 1

Well it would be a positive number

If the opposite is a negative number....then the opposite of that is a positive number..

Which can be resembled as the negative of a negative

-(- 8 1/2)

Answer 2

Why can't it be C? @johnweldon1993

Answer 3

Because when you multiply a positive number by a negative number you get a negative

Answer 4

This is not really going to my mind right now. My logic is that the opposite of 8 1/2 is -8 1/2. Then the opposite of -8 1/2 is 8 1/2. I believe that this is like listing the process of first having the negative 8 1/2 and then put the positive sign outside of it
+(- 8 1/2)

Answer 5

And doesn't A and B resemble the same idea of being positive like this?

Answer 6

Correct it is....but + and + means the opposite was never implemented...

and as you know every time you multiply by a negative you change the sign

Answer 7

So how does multiplication come into finding the opposite of a number?

Answer 10

Well it doesn't really I was just pointing out that whenever you multiply a number by a negative number...you get the opposite sign..

so opposite of 4 is -4...and opposite of that is -(-4)

Answer 11

iirc the opposite just means the negative of the number

Answer 12

The "opposite of the opposite of a postive number " is just the number you started with.
I wouldn't spend too much time on this particular problem....please move on and come back to this problem if you're still not clear what the correct procedure is.
