Given: $5 - [2 - (- 4) + 11 - 8]$ $5-[2-(-4)+11-8]$

Starting with $- (- 4)$ $-(-4)$ this becomes $+ 4$ $+4$ :

$5 - [2 + 4 + 11 - 8]$ $5-[2+4+11-8]$

Combine everything within the brackets:

$5 - [6 + 11 - 8]$ $5-[6+11-8]$

$5 - [17 - 8]$ $5-[17-8]$

$5 - [9]$ $5-[9]$

The brackets can be removed:

$5 - 9$ $5-9$

$- 4 \leftarrow$ $-4 larr$ simplified.
