Answer 1

1. -25 - (-18 +26-40) + (-58+70 - 200) - 6=
Respuesta: -25 – (-32) + (-188) – 6 = -25 + 32 – 188 – 6 = -187

2. -50 – { 36 – [-38 + ( 25 – 50 + 4) – 9] + 12} – 40 =

R: -50 – { 36 – [-38 + (-21) – 9] + 12} – 4
-50 – { 36 – [-38 -21 – 9] + 12} – 4

-50 – { 36 – [- 68] + 12} – 4

-50 – { 36 + 68 + 12} – 4

-50 – ( 116) – 4

-50 – 116 – 4 = -170

3. 40 + (-9 + 18 +36 – 7) – ( -25 + 42 – 23 ) – 14 =

R: 40 + (38) – ( -6 ) – 14

40 + 38 + 6  – 14 = 70
