Answer 1

Hola!

Resolvemos.

300+27×(-2)+(-36)÷3=

=300+−54+−36÷3

=246+−36÷3

=246+−12

=234

2-35+(-12) ÷ (-4)+(-5)x3=

=−33+−12÷−4+(−5)*(3)

=−33+3+(−5)*(3)

=−30+(−5)*(3)

=−30+−15

=−45

3-2x(-5+3)+(4-7)+(-6)x(-4)=

=3−(2)(−2)+4−7+(−6)(−4)

=3−(−4)+4−7+(−6)(−4)

=7+4−7+(−6)(−4)

=7+−3+(−6)(−4)

=4+(−6)(−4)

=4+24

=28

4-18 ÷(-2)+(-10-2)+(-2)×(-5)×3=

=4−(−9)−10−2+((−2)(−5))(3)

=13−10−2+((−2)(−5))(3)

=13+−12+((−2)(−5))(3)

=1+((−2)(−5))(3)

=1+(10)(3)

=1+30

=31

Salu2!!
