See a solution process below:

First, rewrite the term in parenthesis:

#-81 - 13 - [-75 - color(red)((-2))] + 25 =>#

#-81 - 13 - [-75 + color(red)(2)] + 25#

Next, evaluate the term within the brackets:

#-81 - 13 - [color(blue)(-75) + color(red)(2)] + 25 =>#

#-81 - 13 - [color(blue)(-73)] + 25 =>#

#-81 - 13 + color(blue)(73) + 25#

Then, perform the addition and subtraction operations from left to right:

#color(red)(-81) - color(blue)(13) + 73 + 25 =>#

#color(red)(-94) + color(blue)(73) + 25 =>#

#color(red)(-21) + color(blue)(25) =>#

#4#
