Answer 1

Respuesta:

856+(19−3−(6+(5−3)−(2+1)+(5−3)

=856+(16−(6+(2)−(3)+(2)))=  

=856+(16−(8−(3)+(2)))=

=856+(16−(5+(2)))=

=856+(16−(7))=

=856+(9)=

=865

(8+(4−2)+(9−(3+1)

=(8+(2)+(9−(4)))=  

=(10+(5))=

=15

(6−4)−(9−(3−2)−(9−7)−(6−5)

=(2)−(9−(1)−(2)−(1))=  

=(2)−(8−(2)−(1))=

=(2)−(6−(1))=

=(2)−(5)=

=−3

8+(9−(6−(5−4)+14−(11−(7−(3−2)

=8+(9−(6−(1)+14−(11−(7−(1)))))=  

=8+(9−(5+14−(11−(6))))=

=8+(9−(19−(5)))=

=8+(9−(14))=

=8+(−5)=

=3
