Answer 1

Respuesta:

1) ) 2 – 5 x 7 =  -33

2) –5 – (3 + 4 x –6) + 1 = 17  

3) –4 + 6 x –2 ––8 x 7 =  40

4) –18 x 6 ––7 x 6 + –9 =  -75

5) –12 – 24 + 6 x–5 =  -66

6) 4 – 5 ––6 – 7 x 8 + 9 = -42

7) 3 ––5 x 6 ––9 + –3 =  39

8) –7 + [–2 x(3 – 4 x 2) – 1] = 2

9) [–6 – 7 x(5––7) +3] – [23 – 45 x 9] =

10) 3 –{ – [ – ( – 8 ) ] } =
