Answer 1

$\huge\red {\mid {\fbox{\tt {hola}}\mid}}$

+3− (+4) − (− 2) + (+2) − (+3) − (- 4) =

3−4−(−2)+2−3−(−4)

=−1−(−2)+2−3−(−4)

=1+2−3−(−4)

=3−3−(−4)

=0−(−4)

=4

+3- (-2) + (-4) + (+2) - (-3) - (+2) =

3−(−2)−4+2−(−3)−2

=5−4+2−(−3)−2

=1+2−(−3)−2

=3−(−3)−2

=6−2

=4

-2 − (+2) - (+3) − (-4) + (+6)=

−2−2−3−(−4)+6

=−4−3−(−4)+6

=−7−(−4)+6

=−3+6

=3

+5 - (+2)-(-3) + (-2) - (+4)=

5−2−(−3)−2−4

=3−(−3)−2−4

=6−2−4

=4−4

=0

-3 − (+2) – (-4) + (-3) − (+1) − (+3) =

−3−2−(−4)−3−1−3

=−5−(−4)−3−1−3

=−1−3−1−3

=−4−1−3

=−5−3

=−8
