Question

-(-3 + 2 - 1 + (-1 – 2)) + [4-(-3) + (1 - 4)] +-3-[-2 + 1] - 4​

Answer 1

Respuesta:

−(−3+2−1−1−2)+4−(−3)+1−4−3−(−2+1)−4

=−(−1−1−1−2)+4−(−3)+1−4−3−(−2+1)−4

=−(−2−1−2)+4−(−3)+1−4−3−(−2+1)−4

=−(−2+−3)+4−(−3)+1−4−3−(−2+1)−4

=−(−5)+4−(−3)+1−4−3−(−2+1)−4

=5+4−(−3)+1−4−3−(−2+1)−4

=5+7+1−4−3−(−2+1)−4

=5+7+−3−3−(−2+1)−4

=5+4−3−(−2+1)−4

=9−3−(−2+1)−4

=6−(−2+1)−4

=6−(−1)−4

=7−4

=3
