Neka je ''S'' [[Skup (matematika)|skup]] s nekom [[Binarna operacija|binarnom operacijom]] *. <br />
<br />
Pretpostavimo u <i>(S,*)</i>, skupu S sa binarnom operacijom *, vrijedi sljedeće:<br />
* postoji [[Neutralni element|neutralni element]] ''e''<br />
* za neke elemente a i b iz S vrijedi ''a*b=e''<br />
<br />
Tada se ''a'' zove '''lijevi inverz''' od ''b'', a ''b'' se zove '''desni inverz''' od ''a''. <br />
<br />
Ako je neki element ''x'' i lijevi i desni inverz od ''y'', onda se ''x'' zove '''obostrani inverz''', ili jednostavnije '''inverz''' od ''y''. Za element koji ima obostrani inverz u ''S'' kažemo da je '''invertibilan''' u ''S''.<br />
