\(\left(413-127+42\right)-\left(413+127-48\right)\)
\(=413-127+42-413-127+48\)
\(=\left(413-413\right)-\left(127+127\right)+\left(42+48\right)\)
\(=-254+90=-164\)
( 413 - 127 + 42 ) - ( 413 + 127 - 48 )
= 413 - 127 + 42 - 413 - 127 + 48
= ( 413 - 413 ) + ( 127 - 127 ) + ( 42 - 48 )
= 0 + 0 + ( -6 )
= -6
( 413 - 127 + 42 ) - ( 413 + 127 - 48 )
= 413 -127 + 42 - 413 - 127 + 48
= ( 413 - 413 ) - ( 127 - 127 ) + 42
