  1. 1) ( – 15 ) + ( + 20 ) = 5
    2) ( – 17 ) + ( + 12 ) = – 5
    3) ( – 13 ) + ( + 18 ) = 5
    4) ( – 20 ) + ( + 14 ) = – 6
    5) ( – 25 ) + ( + 34 ) = 9
    6) ( + 50 ) + ( – 14 ) =36
    7) ( + 18 ) + ( – 5 ) = 13
    8) ( + 12 ) + ( – 24 ) = – 12
    9) ( + 14 ) + ( – 27 ) = – 13
     

  2. $\text{1) (- 15) + ( + 20)}$ = $\text{- 15 + 20}$ = $\text{5}$
    $\text{2) (- 17) + (+ 12)}$ = $\text{- 17 + 12}$ = $\text{- 5}$
    $\text{3) ( – 13) + (+ 18)}$ = $\text{- 13 + 18}$ = $\text{5}$
    $\text{4) (- 20) + (+ 14)}$ = $\text{- 20 + 14}$ = $\text{- 6}$
    $\text{5) (-25)+ (+ 34)}$ = $\text{- 25 + 34}$ = $\text{9}$
    $\text{6) (+ 50) + (- 14)}$ = $\text{50 – 14}$ = $\text{36}$
    $\text{7) (+ 18) + (- 5)}$ = $\text{18 – 5}$ = $\text{13}$
    $\text{8) (+ 12) + (- 24)}$ = $\text{12 – 24}$ = $\text{- 12}$
    $\text{9) (+ 14) + (- 27)}$ = $\text{14 – 27}$ = $\text{- 13}$
