Answer 1

$a) - 3 \times ( - 2) + 3 + 5 {}^{0} \\ 6 + 3 + 1 \\ 9 + 1 \\ \color{red}10$

$b) - 1 + 3 + 2 \times ( + 5) \\ - 1 + 3 + 10 \\ 2 + 10 \\ \color{red}12$

$c) - 2 \times ( - 7) + 3 {}^{2} \\ 14 + 9 \\ \color{red}23$

$d)2 \times ( - 5) - 3 \times 1 {}^{3} + 4 \\ - 10 - 3 \times 1 + 4 \\ - 10 - 3 + 4 \\ - 13 + 4 \\ \color{red} - 9$
