2) 35.(-2)-[18-40:(-8)]
3) 7[-14+20:(-5)].(-2)
4) 12 +[(-3) -(6-9).2]
5) (-15)-[(-12)+(5-15)]​

Answer 1

Respuesta:

1) 13[20-(-10)2]-18/-9

=13[20-20]-18/-9

=13[0]-18/-9

=-18/-9

=2

2) 35.(-2)-[18-40:(-8)]

= -70-[-22/-(8)]

= -70 + 11/4

= (-240 +11)/4

= -229/4

3) 7[-14+20:(-5)].(-2)

= 7[6/-5](-2)

=84/-2

4) 12 +[(-3) -(6-9).2]

 = 12+[-3 +6]

= 12 + 3

=15

5) (-15)-[(-12)+(5-15)]​

= -15-[-12-10]

=-15+22

=7
