Answer:

The opposite is what adds up to #0#
The reciprocal is what multiplies to #1#

Explanation:

Opposite : reverse the sign, because #x# added to #-x# always adds up to #0#

Reciprocal : make the denominator and numerator change places, because #x/y*y/x# multiplies to #1#

In your case they are #4//2and -2//4# respectively.
(You might have written the original number as #-2#
The answers would then have been #2and-1//2#)
