Question

Simplify each of the following a) 7+(-1+2)-(6-4) b) -8-(-2+5)-(-1-2) c) 7-(-2)-(2-1) d) -13+(5-5)-(-8-8)+3.Solve these solutions by step by step

Answer 1

Answer:

a) 6

b) -8

c) 8

d) 3

Step-by-step explanation:

a) -1+2 = 1

6-4 = 2

so,

7 + 1 - 2

= 6

b) -2+5 = 3

-1-2 = -3

so,

-8-3-(-3)

= -8-3+3

= -11+3

= -8

c) 2-1 = 1

so,

7 + 2 - 1

= 8

d) 5-5 = 0

-8-8 = -16

so,

-13 + 0 + 16

= 16 - 13

= 3

Hope it helps

Answer 2

Answer:

Step-by-step explanation:

(a) 7+(-1+2)-(6-4)

     = 7 + 1 - 2

     = 8 - 2

     = 6

(b)-8-(-2+5)-(-1-2)

   = -8 - 3 - (-3)

   = -8 - 3 + 3

   = -8 - 6

  = -14

(c)   7-(-2)-(2-1)

     = 7 +2 - 1

     =9 -1

     = 8

d) -13+(5-5)-(-8-8)+3

  =  -13 + 0 +16 +3

   = -13 + 19

    = 6
