Evaluate the brackets first.
The result is #-2#.

Explanation:

When evaluating this kind of expressions, remember to always evaluate the brackets first.

So, let's start with the inner brackets:

# (2 - (1 * 6) - ( 9 - 5)) -: 4#

# = (2 - (color(blue)(1 * 6)) - ( 9 - 5)) -: 4#

# = (2 - color(blue)(6) - ( 9 - 5)) -: 4#

# = (2 - (6) - (color(blue)( 9 - 5))) -: 4#

# = (2 - (6) - (color(blue)(4))) -: 4#

# = (2 - 6 - 4) -: 4#

# = (color(blue)(2 - 6) - 4) -: 4#

# = (color(blue)(-4) - 4) -: 4#

# = (-4 - 4) -: 4#

# = (color(blue)(-4 - 4)) -: 4#

# = (color(blue)(-8)) -: 4#

# = -8 -: 4#

# = color(blue)(-8 -: 4)#

# = color(blue)(-2)#

# = -2#
