Question

realiza las siguientes operaciones con números enteros
a) (7-2+4)-(2-5)
b) 1-(5-3+2)- [ 5-(6-3+1)-2]
c)3-12*3+18:(-12:6+8)

Answer 1

Explicación paso a paso:

a) (7-2+4) - (2-5) =

= (5 +4) - (-3) =

= 9 + 3 =

= 12

b) 1-(5-3+2) - [5-(6-3+1)-2] =

= 1- ( 2+2) - [5- (3+1)-2] =

= 1- (+4) - [5- (+4)-2] =

= 1-4 - (5-4-2) =

= -3 - (-1) =

= -3 +1 =

= -2

c) 3-12^3+18 ÷ (-12÷6+8) =

= 3- 1728 + 18 ÷ ( -2+8) =

= 3 - 1728 + 18 ÷ 6 =

= 3 - 1728 +3

= - 1722
