Question

(-5+2) . (-2+5)+(-8+9) . (-1) +0 . (-3)

-130+(-4) . (8+4:2) : (-2) - 25 : (15-20)+ 3

Answer 1

Ejercicio 1. : Respuesta -10

(-5+2) . (-2+5)+(-8+9) . (-1) +0 . (-3)

=−3(−2+5)+(−8+9)(−1)+(0)(−3)

=(−3)(3)+(−8+9)(−1)+(0)(−3)

=−9+(−8+9)(−1)+(0)(−3)

=−9+(1)(−1)+(0)(−3)

=−9+−1+(0)(−3)

=−10+(0)(−3)

=−10+0

=−10

Ejercicio 2. : Respuesta: -102

=−130+−4(8+2)÷−2−25÷15−20+3

=−130+(−4)(10)÷−2−25÷15−20+3

=−130+−40÷−2−25÷15−20+3

=−130+20−25÷15−20+3

=−110−÷2515−20+3

=−110−÷25−5+3

=−110−(−5)+3

=−105+3

=−102
