Answer 2

$a) \large{( + 3) + ( - 2) + ( - 5)} \\ \large{3 - 2 - 5} \\ \large{3 - 7} \\ \large \boxed{ \red{ - 4}}$

______________________________________

$\large{b)( - 2) - ( + 1) - ( + 5)} \\ \large { - 2 - 1 - 5} \\ \large{ - (2 + 1 + 5)} \\ \large \boxed{ \red{ - 8}}$

______________________________________

$\large{c)( + 4) + ( - 2) - ( + 3)} \\ \large{4 - 2 - 3} \\ \large{4 - 5} \\\large \boxed{ \red{ - 1}}$

______________________________________

$\large{d)( + 5) - ( - 3) - ( - 1)} \\ \large{5 + 3 + 1} \\ \large{8 + 1} \\ \large \boxed{ \: \red{ 9 \: }}$
