*****Is your question looking for the opposite and reciprocal separately?  Or together?

how do you know whether the rec. if positive or negative?..im kinda confused on that. is it always 1/ whatever the number is? like i have 3 so opp: -3 and rec: 1/3 or -1/3?..

The opposite just reverses the sign.

The reciprocal keeps the same sign, just puts a one over it.

the rec. keeps the same sign as the original number?
