Answer:

Step-by-step explanation:

i m writting only the answer

1. (i)57

  (ii)0

  (iii)-2054

2.(i)100

  (ii)-499

  (iii)202

3.(i)-9

  (ii)-15

  (iii)-301

4.(i)(-145)+79+(-200)+2

    79+2-145-200

    81-345

    -264

(ii)100+(-790)+(-38)+44+(-1)

  100+44-790-38-1

  144-829

  -685

5.(i)  l 37-(-8) l

     =  l 37+8 l

     = l45 l

     =  45

(ii) [-13-(-17)]+[-22-(-40)]

    [-13+17]+[-22+40]

    4+18

    22

(iii) l (-37) l-l (10) l

     37-10

     27

(iv)[37-12]-[15-(-18)]

   [25]-[15+18]

   25-33

   -8

6.Sum=-10

  one number=170

  let the other number be x

  A.T.Q.

  x+170=-10

  x=-10-170

  x=-180

 so, the other number is -180

7. (-23)-[(-1050)+813]

   (-23)-[-1050+813]

   (-23)-[-237]

   -23+237

   214
