Question

I Resoluer : A+BA+C,C+B, A+D
A= -7-3-2
B=(-(-4) +(-3)-2(-5))
C=}-7-4-2(-3)-(-4)}
D=(1-3-(-4)-(-7)}​

Answer 1

A:

-7-3-2

=−10−2

=−12

B:

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

=4−3−(2)(−5)

=1−(2)(−5)

=1−(−10)

=11

C:

-7-4-2(-3)-(-4)}

=−11−(2)(−3)−(−4)

=−11−(−6)−(−4)

=−5−(−4)

=−1

D:

(1-3-(-4)-(-7)}

=−2−(−4)−(−7)

=2−(−7)

=9
