Question

What is negative inverse, positive inverse and multiplicative inverse?

Answer 1

negative inverse eg -5 is +5, positive inverse eg 2 is -2 and multiplicative inverse eg 7 is 1/7

Answer 2

I think negative inverse is -5 ->1/5

Answer 3

You are right moongazer. Makes more sense, thanks

Answer 4

so is the positive inverse the same as the multiplicative inverse?

Answer 5

i'm a little rusty on these definitions. does anyone else have any input?

Answer 6

i think this is non-standard terminology "negative inverse"
but my guess would be "negative reciprocal"
\[m, -\frac{1}{m}\]

Answer 7

That is what my teacher taught us.

Answer 8

then again i could be totally wrong. because later the question says "multiplicative inverse" so maybe it is what zed wrote. is this the whole question?

Answer 9

I haven't come across this terminology before.

Answer 10

i'll tell that to my teacher. :)

Answer 11

w8 I think my teacher is correct.

Answer 13

if you have an operations
\[\oplus\] with identity
\[e\] then the inverse of an element
\[x\] is the unique element
\[x'\] with
\[x\oplus x'=x'\oplus x=e\]
there is no such thing as a "negative inverse"

Answer 14

look at that. I think we just have different kinds of terminologies. :)

Answer 15

ohh i wasn't saying your teacher was wrong just that i haven't seen this before

Answer 16

thanks (:

Answer 17

ok well if you weren't saying it, i was

Answer 18

there is a "negative reciprocal" but not a "negative inverse" the more i think about it, the less sense it makes

Answer 19

Which do you think is proper "negative inverse" or "negative reciprocal"?

Answer 20

That's why I am getting confused about it.

Answer 21

interesting satellite. i seem to be getting more confused as well. i don't like the words

Answer 22

a quick google search will turn up nothing.

Answer 23

I'll just ask my teacher if negative reciprocal is the same as negative inverse. If it is, I would chose the term negative reciprocal. :)

Answer 24

i was able to find http://en.wikipedia.org/wiki/Multiplicative_inverse
which interchanged inverse and reciprocal

Answer 25

but that was only for multiplicative inverse not the others

Answer 26

there is "additive inverse"
multiplicative inverse
and then something totally different

negative correlation
inverse correlation

but no "negative inverse"

Answer 27

yes even wiki hasn't heard of "negative inverse'
maybe your teacher made it up one evening

Answer 28

Maybe during the time of my teacher they call negative reciprocal as negative inverse.

Answer 29

Yeah I have never heard of negative inverse

Answer 30

maybe...

Answer 31

satellite can you help asap

Answer 32

not related to math

Answer 33

this link goes to this thread lol

Answer 34

or anyone else

Answer 38

i think your right doodle

Answer 39

Maybe the teacher was talking about the additive inverse, which the additive inverse is the negative . The additive inverse of 3 is -3, and the negative inverse of -3 is the positive 3

Answer 40

never heard of negative or positive inverse.
the inverse element postulates of addition and multiplication are
additive inverse and multiplicative inverse/reciprocal
additive inverse is the opposite of a number such that the sum = 0
a + -a or 1/a + -1/a or -a + (+a) ...
multiplicative inverse such that the product = 1
a * 1/a
