Question

(-50+19+143)-(-79+25+48)

Answer 1

(-50 + 19 + 143)-(-79 + 25 +48)

= (-31 + 143 ) - (-54 + 48 )

= 112 - (-6)

= 112 + 6

= 118

Answer 2

 \(\left(-50+19+143\right)-\left(-79+25+48\right)\) 

\(=-50+19+143+79-25-48\)

\(=-50-25+\left(79-48+19\right)+143\) 

\(=-75+50+143\)

\(=-25+143\) 

\(=118\)
