- 5 – 8 – [ -4 + 2 – (10 + 8 – 11) + 2] – [-7 + 5 – (2 + 6)]

=−13−(−4+2−(10+8−11)+2)−(−7+5−(2+6))

=−13−(−2−(10+8−11)+2)−(−7+5−(2+6))

=−13−(−2−(18−11)+2)−(−7+5−(2+6))

=−13−(−2−7+2)−(−7+5−(2+6))

=−13−(−9+2)−(−7+5−(2+6))

=−13−(−7)−(−7+5−(2+6))

=−6−(−7+5−(2+6))

=−6−(−2−(2+6))

=−6−(−2−8)

=−6−(−10)
