d- - (5 – 2) + (4 – 6) – (8 + 2) =

Answer 1

a- - 6 + 5 - (7 - 4) + 3=

b- - 2 – 5 – (2 – 7) – (5 + 6) =

c- 3 – 7 + (- 9 – 3) – (1 – 2) =

d- - (5 – 2) + (4 – 6) – (8 + 2) =

Explicación paso a paso:

a- - 6 + 5 - (7 - 4) + 3=

   -6+5-7-4+3=

                 -9=

b- - 2 – 5 – (2 – 7) – (5 + 6) =

   -2-5-2-7-5+6=

               -21+6=

                   -15=

c- 3 – 7 + (- 9 – 3) – (1 – 2) =

     -3-7+9-3-1-2=

                    -10=

d- - (5 – 2) + (4 – 6) – (8 + 2) =

      -5-2+4-6-8+2=
