Solution

Step:Simplification.
$∴ 56 - (- 9) + (- 6) - (- 4) + (- 41)$ $= 56 + 9 + (- 6) + 4 + (- 41)$ $[∵ - (- 9) = 9, - (- 4) = 4]$
$= (56 + 4) + 9 + [(- 6) + (- 41)]$ (Using the associative property of addition of integers)
$= 60 + 9 + (- 47)$
$= (60 + 9) + (- 47)$ (Using the associative property of addition of integers)
$= 69 + (- 47)$
$= 22$
Therefore, the required answer is $22$ .
