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

    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?

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

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

    That is what my teacher taught us.

    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?

    I haven't come across this terminology before.

    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"

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

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

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

    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. :)

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

    but that was only for multiplicative inverse not the others

    there is "additive inverse" multiplicative inverse and then something totally different negative correlation inverse correlation but no "negative inverse"

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

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

    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

    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
