C) (+3) + (-10) =
d) (-5) - (+8)
e) (+3) - (+5) =
1) (-1) – (-2) =
​

Answer 1

$a)( + 4) + ( + 1) + ( + 8) \\ 4 + 1 + 8 \\ 5 + 8 \\ \boxed{13}$

______________________________________

$b)( - 9) + ( - 4) + ( - 3) \\ - 9 - 4 - 3 \\ - 13 - 3 \\ \boxed{ - 16}$

______________________________________

$c)( + 3) + ( - 10) \\ 3 - 10 \\ \boxed{ - 7}$

______________________________________

$d)( - 5) - ( + 8) \\ - 5 - 8 \\ \boxed{ - 13}$

______________________________________

$e)( + 3) - ( + 5) \\ 3 - 5 \\ \boxed{ - 2}$

______________________________________

$f)( - 1) - ( - 2) \\ - 1 + 2 \\ \boxed{1}$
