Answer 1

1)     (+2) + (–3) + (+3) + (–5) +  (–2) = –5

 

2)      (–2)+(–7)+(+3)+(–4)+(–11)= –21

 

3)      (–7) –  (– 4) +(–5) + (–10) + (– 2) – (–13) =  –7

 

4)      (+8)–(–4)–(+4)–(+10)–(–5)–(–8) = 11

 

5)      –2 + 8 –8 + 10 –20 + 5 – 7 = –14

 

6)      9–7+11–20+12–23+5–5–12 = –30

 

7)      3– { 4 – 7 – [–5–7 + (6 – 7+ 5 ) ] } +8 = 6

 

8)      5+[–5+10–{2–9+(–8+2)}] – 6 +7 =24

 

9)      – [ –{ – (–6+5 – 10+3 –15 ) }] =  23

 

10)                        – { – [ – ( –20 +15 –7) – 8]– 6 }+7–(–3) = 20

 

11)                        (+12) x (–15) = –180

 

12)                       (–80) x (–3) = –240

 

13)                        (– 5)x(+8)x(–7)x(–2)= –560

 

14)                        (– 216) x (+32) = –6.912

 

15)                        (–98.745) x(–756) = 74.651.220

 

16)                        (–450) ¸ (–9) = 50

 

17)                         (+68.745)  ¸ (–5) = 13.749

18)                        (–6.913.536) ¸ (–56) =  123.456

19)                        (+1.584.312) ¸ (+789) = 2.008

20)                        (92.643.240) ¸ (–908)  =   102.030
