$\\ { \large \displaystyle \sf {a) \: - ( - 18) + 32 }} \\ { \large \displaystyle \sf { + 18 + 32}} \\ {\large \displaystyle \sf \boxed{ \red{{ + 50}}}}$

${ \large \displaystyle \sf {b) \: + 51 - (76) }} \\ { \large \displaystyle \sf { + 51 - 76}} \\ {\large \displaystyle \sf \boxed{ \red{{ - 25}}}}$

${ \large \displaystyle \sf {c) \: 86 - ( + 95) }} \\ { \large \displaystyle \sf { 86 - 95}} \\ {\large \displaystyle \sf \boxed{ \red{{ - 9}}}}$
