Answer 1

Respuesta:

1. 12–3 + (–4) = 9 + (–4) = 9 - 4= 5

2. 4+(–2)– (–3) – (–1) = 2– (–3) – (–1) = 2+3 – (–1) = 5 – (–1) = 5 + 1 = 6

3. 5• (–12 + 4) = 5• (–8) = -40

4. –4• (–3)+ (–3) = 12 + (–3) = 9

5. –(–3)• (–3) = 3• (–3) = -9

6. 4• (4–2) = 4• (2) = 8

7. –5• (–12+4) = –5• (-8) = 40

8. –4• (–2–3) – 1 = –4• (–5) – 1 = 20 – 1 = 19

9. –1• (–2)+( –2)• ( –3)• (–1) = 2+6• (–1) = 8• (–1) = -8  

10. 4 – 20/(–5) = 4 – (-4) = 4 + 4 = 8

11. 25/(–5) – 1+(7+(-4))= (-5) – 1+(3) = (-6) + 3 = -3

12. –3•(–2)•(–1) – 6/3 = 6•(–1) – 2 = (-6)– 2  = -8

13. –10 – (–2)•(–1)•(–3) = –10 – 2•(–3) = –10 – 6 = –16

14. –3•(–4 +(–2)) = –3•(-6) = 18
