5-18+{2-[-11+3-(-7)+3]+8}+4​

Answer 1

Respuesta:

Explicación paso a paso:

12-11{4- [8+ (-10)-7]-13}-7

12−11(4−(8−10−7)−13)−7

=12−11(4−(−2−7)−13)−7

=12−11(4−(−9)−13)−7

=12−11(13−13)−7

=12−(11)(0)−7

=12−0−7

=12−7

=5

5-18+{2-[-11+3-(-7)+3]+8}+4​

5−18+2−(−11+3−(−7)+3)+8+4

=−13+2−(−11+3−(−7)+3)+8+4

=−13+2−(−8−(−7)+3)+8+4

=−13+2−(−1+3)+8+4

=−13+2−2+8+4

=−13+0+8+4

=−13+8+4

=−5+4

=−1
