Explanation:

(((−2)xx(0.14))xx(−3))xx(0.5)(((−2)×(0.14))×(−3))×(0.5)

=((−0.28)xx(−3))xx(0.5)=((−0.28)×(−3))×(0.5)

=(0.84)xx(0.5)=(0.84)×(0.5)

=0.42=0.42

color(red)(0.42)0.42

Explanation:

-2(0.14)(-3)(0.5)−2(0.14)(−3)(0.5)

color(white)("XXX")=2xx(0.14)xx(3)xx(0.5)color(white)("xxx")XXX=2×(0.14)×(3)×(0.5)xxxmultiplying 2 negatives gives a positive

color(white)("XXX")=(0.14)xx(3)xx(2)xx(0.5)color(white)("xxx")XXX=(0.14)×(3)×(2)×(0.5)xxxrearrange to simplify

color(white)("XXX")=(0.14)xx(3)color(white)("xxxxxxxxxxxxxx"XXX=(0.14)×(3)xxxxxxxxxxxxxxsince 2xx0.5=12×0.5=1

color(white)("XXX")=0.42XXX=0.42
