Answer 1

$a) \\ \LARGE{}10 - ( - 3 + 5) \\ \LARGE{} + (5 - 3) \\ \LARGE{}2 \\ \LARGE{}10 - 2 \\ \LARGE\boxed{8}$

$b) \\ \LARGE{}( - 5 + 2) - ( - 3 + 1) \\ \LARGE{} - (5 - 2) \\ \LARGE{} - 3 \\ \LARGE{}( - 3) - ( - 3 + 1) \\ \LARGE{} - (3 - 1) \\ \LARGE{} - 2 \\ \LARGE{}( - 3) - ( - 2) \\ \LARGE{} - 3 - ( - 2) \\ \LARGE{} - 3 + 2 \\ \LARGE{} - (3 - 2) \\ \LARGE\boxed{ - 1}$
