Question

•Daca a=-11, b+c=89, calculati c+a+b
•Daca a+b=-71,c+d=+26, calculati (a+b)+(d+c)
•Daca a+c=-7,b+d=-35,calculati (a+b+c)+d

Answer 1

1. c+a+b = a+b+c= -11 + 89 = 78
2. (a+b) + (d+c) = -71 + 26 = -45
3. (a+b+c)+d = a+b+c+d = a+c+b+d = -7 + (-35) = -7 - 35 = -42

Answer 2

 c + a + b= -11+ 89 = 78

  (a + b) + (d + c) = - 71 + 26 = - 45

 (a + b + c) + d =  - 7+(- 35) = - 42
