1) –(-15) – (-3 + 7 – 8) – |-5|
$= 15- (-4) -5$
$= 14$
2) -17 – (-3 + 8 – |-12|) + (-13)
$= -17-(-3+8-12)-13$
$= -17-(-7)-13$
$= -23$
3) –(-3 + 7 – 13) + (-5 + 4 – 8)
$= -(-9)+(-9)$
$= 0$
4) (6 – 5 + 3) – (-13 + 7) – |-5|
$= 4-(-6)-5$
$= 5$
5) (-|-5| + 3 – 10) – |3 – 5 – 4|
$= (-5+3-10)-|-6|$
$= -12-6$
$= -18$
