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

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

You are right moongazer. Makes more sense, thanks

so is the positive inverse the same as the multiplicative inverse?
anonymous
  • anonymous
i'm a little rusty on these definitions. does anyone else have any input?
anonymous
  • anonymous
i think this is non-standard terminology "negative inverse" but my guess would be "negative reciprocal" \[m, -\frac{1}{m}\]
moongazer
  • moongazer
That is what my teacher taught us.
anonymous
  • anonymous
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?
anonymous
  • anonymous
I haven't come across this terminology before.
moongazer
  • moongazer
i'll tell that to my teacher. :)
moongazer
  • moongazer
w8 I think my teacher is correct.

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"
moongazer
  • moongazer
look at that. I think we just have different kinds of terminologies. :)
anonymous
  • anonymous
ohh i wasn't saying your teacher was wrong just that i haven't seen this before
anonymous
  • anonymous
thanks (:
anonymous
  • anonymous
ok well if you weren't saying it, i was
anonymous
  • anonymous
there is a "negative reciprocal" but not a "negative inverse" the more i think about it, the less sense it makes
moongazer
  • moongazer
Which do you think is proper "negative inverse" or "negative reciprocal"?
moongazer
  • moongazer
That's why I am getting confused about it.
anonymous
  • anonymous
interesting satellite. i seem to be getting more confused as well. i don't like the words
anonymous
  • anonymous
a quick google search will turn up nothing.

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. :)
anonymous
  • anonymous
i was able to find http://en.wikipedia.org/wiki/Multiplicative_inverse which interchanged inverse and reciprocal
anonymous
  • anonymous
but that was only for multiplicative inverse not the others
anonymous
  • anonymous
there is "additive inverse" multiplicative inverse and then something totally different negative correlation inverse correlation but no "negative inverse"
anonymous
  • anonymous
yes even wiki hasn't heard of "negative inverse' maybe your teacher made it up one evening
moongazer
  • moongazer
Maybe during the time of my teacher they call negative reciprocal as negative inverse.
anonymous
  • anonymous
Yeah I have never heard of negative inverse
anonymous
  • anonymous
maybe...

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
anonymous
  • anonymous
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
