Question

9. Efectuar: A = 5 -[-3-(-4-7(-3) - 9)] + 6 B = 6 + [4 + (-8 - (+6) - 5)] - 9 C = -8-1-3 - [7 +(-3 - 1)] - 7}+3 Calcular: A -C-B​

Answer 1

-4

Explicación paso a paso:

1.

A= 5 -[-3-(-4-7(-3) - 9)] + 6

A= 5- [-3-(-4+21-9]+6

A= 5-[-3-(8)]+6

A= 5-[-3-8]+6

A= 5-[-11]+6

A= 5+11+6

A=22

2.

B= 6 + [4 + (-8 - (+6) - 5)] - 9

B= 6 + [4 + (-8 - 6 - 5)] - 9

B= 6 + [4 + (-19)] - 9

B= 6 + [4 -19] - 9

B= 6 + [-15] - 9

B= 6 - 15 - 9

B= 6 - 24

B= - 18

3.

C=-8-{-3-[7+(-3-1)]-7}+3

C=-8-{-3-[7+(-4)]-7}+3

C=-8-{-3-[7-4]-7}+3

C=-8-{-3-[3]-7}+3

C=-8-{-3-3-7}+3

C=-8-{-13}+3

C=-8+13+3

C=-8+16

C=8

22-8-18

22-26

- 4

Answer 2

A:

5 -[-3-(-4-7(-3) - 9)] + 6

=5−(−3−(−4−(−21)−9))+6

=5−(−3−(17−9))+6

=5−(−3−8)+6

=5−(−11)+6

=16+6

=22

B:

6 + [4 + (-8 - (+6) - 5)] - 9

=6+4+−14−5−9

=6+4+−19−9

=6+−15−9

=−9−9

=−18

C:

-8-1-3 - [7 +(-3 - 1)] - 7}+3

=−9−3−(7−3−1)−7+3

=−12−(7−3−1)−7+3

=−12−(7+−4)−7+3

=−12−3−7+3

=−15−7+3

=−22+3

=−19
