Question

-{1-[2-3(1-7)]+6-[-1+5-4(6-3)]} con esplicacion

Answer 1

-{1-[2-3(1-7)]+6-[-1+5-4(6-3)]}

=−(1−(2−(3)(−6))+6−(−1+5−4(6−3)))

=−(1−(2−(−18))+6−(−1+5−4(6−3)))

=−(1−20+6−(−1+5−4(6−3)))

=−(−19+6−(−1+5−4(6−3)))

=−(−13−(−1+5−4(6−3)))

=−(−13−(4−4(6−3)))

=−(−13−(4−(4)(3)))

=−(−13−(4−12))

=−(−13−(−8))

=−(−5)
