resuelve las siguientes operaciones con números enteros:
-------------------------------------------------------------------------------------------------
5.(-2)+3:(-3)-4=
-------------------------------------------------------------------------------------------------
-25:(-5)-4.3+2.2=
------------------------------------------------------------------------------------------------
-1+7(2-4.3)-10=
------------------------------------------------------------------------------------------------
-20:(-5)-(4-6:2)=

Answer 1

5. (-2) + 3 : (-3) - 4 =
-10 + 3 : -7 =
-7 : -7 = 1

-25 : (-5) -4 . 3 + 2.2 =
-25 : (-5 ) - 12 + 4=
-25 : - 13 =
1.923  = 1923 x10 ^-3

-1 + 7(2 - 4.3) - 10 =
-1 + 7 (2 - 12) - 10 =
-1 + 14 - 84 -10 =
-81

-20: (-5) - (4 - 6: 2 ) =
-20 : -5 - (4 - 3) =
-20 : -5 - 4 + 3 =
-20 : -6 =
3.333 = 3333 x 10^ -3
