Question
Find the value of: $38 - (-25) - 58 + (-15) + 23 - (-8)$

Answer

$38 - (-25) - 58 + (-15) + 23 - (-8)$
$ = 38 - (-25) - 58 + (-15) + 23 + 8 $
$= 38 - (-25) - 58 + (-15) + 31$
$ = 38 - (-25) - 58 + (31 - 15) $
$= 38 - (-25) - 58 + 16 $
$= 38 - (-25) - (58 - 16)$
$ = 38 - (-25) - 42 $
$= 38 + 25 - 42 $
$= 38 - (42 - 25)$
$ = 38 - 17 $
$= 21$
Hence, $38 - (-25) - 58 + (-15) + 23 - (-8) = 21$
