$\large\boxed{\begin{array}{l} \rm{( + 27) + ( + 13) + ( - 28)} \\ \rm{27 + 13 + ( - 28) } \\ \rm{27 + 13 - 28} \\ \rm{40 - 28} \\ \huge \boxed{ \boxed{ \boxed{\boxed{ \rm12}}}}\end{array}}$

$\large\boxed{\begin{array}{l} \rm{( - 50) + ( - 30) + ( - 12)} \\ \rm{ - 50 - 30 - 12} \\ \huge \boxed{ \boxed{ \boxed{ \boxed{ \rm{ - 92}}}}}\end{array}}$

$\large\boxed{\begin{array}{l} \rm{( - 11) + ( + 20) + ( + 35)} \\ \rm{( - 11) + 20 + 35} \\ \rm{ - 11 + 20 + 35 } \\ \rm{ - 11 + 55} \\ \huge \boxed{ \boxed{ \boxed{ \boxed{ \rm{44}}}}}\end{array}}$
