${ \large \displaystyle \sf {a) \: 25 - (10 - 1 - 3)}}$

${ \large \displaystyle \sf { 25 - ( 9- 3)}}$

${ \large \displaystyle \sf { 25 -6}}$

$\boxed{ \boxed{ \pink{{ \large \displaystyle \sf { \: \: 19 \: \: }}}}}$

${ \large \displaystyle \sf {b) \: 45 - 18 + 3 + 1 - 2}}$

${ \large \displaystyle \sf {49 - 18 - 2}}$

${ \large \displaystyle \sf {31 - 2}}$

$\boxed{ \boxed{ \pink{{ \large \displaystyle \sf { \: \: 29 \: \: }}}}}$
