"Inverse" can be ambiguous. Are you talking about the additive inverse? Multiplicative? Function-wise?
Reciprocal is what we call the multiplicative inverse.

You do know the group R^+ has no notion of "multiply" right you fucking retard? Any notion of multiplication in R as an operation has the algebraic group structure inherited from R*. Learn basic algebra first stupid freshman,

Leave the OP exactly the same but replace "reciprocal" with inverse. The expression becomes
>he divides numbers instead of just multiplying by it's inverse
R is a FIELD you triple nigger. There are multiple inverses associated with it. Yes, it is possible to multiply by an additive inverse in R^*^+

>multiplying by it's inverse
"Multiply" already directly implies the group structure from R* and hence "inverse" here would refers to the inverse in said group, you fucking complete imbecile.
>R^*^+
LMFAO, you do know R_+ is not a group under addition right? The only "inverse" that'd make sense in R_+ is the multiplicative inverse you fucking idiot.

I must have misinterpreted your gay ass notation. Either way, OP said nothing about positive numbers, he just said NUMBERS.
>hurr positive numbers aren't a group
you're just arbitrarily constricting the OP to make it look like the word reciprocal isn't MORE SPECIFIC AND CLEAR than the word inverse. I bet you're a pure maths major.

Misunderstood*, because you've obviously never read a single abstract algebra book in your entire pathetic life LMAO.
>OP said nothing about positive numbers
Neither did I in >>9894588 nor >>9894607.
>he just said NUMBERS
He said "multiplying" numbers, which implies that he's using the group structure from R*, like literally by fucking definition.
>you're just arbitrarily constricting the OP
You're the one who brought up positive numbers (i.e. R_+), or do you not understand what R* means? (this is a rhetorical question btw, don't answer this)
>reciprocal isn't MORE SPECIFIC AND CLEAR
It literally isn't. Even if we're clear that we're talking about the multiplicative inverse, "reciprocal' implies that the group is Abelian, which is NOT the case in the quarternion NUMBERS.
>I bet you're a pure maths major.
I'm doing a PhD actually.
