\(-8.4+19=-32+19=-13\)

\(-11.3-28=-33-28=-61\)

\(4.\left(-15\right)-18=-60-18=-78\)

\(19-4.\left(-12\right)=19+48=67\)

\(-25.\left(-3\right)-54=75-54=21\)

\(-16-7.\left(-4\right)+24\div\left(-8\right)=-16+28-3=9\)

\(15\div\left(-3\right)+30-7.\left(-3\right)=-5+30+21=46\)

\(-48\div\left(-4\right)+15.\left(-5\right)=12-75=-63\)

\(-29+65\div\left(-5\right)+23=-29-13+23=-19\)

\(15\div\left(-5\right)-17-12.\left(-5\right)=-3-17+60=40\)

\(28.\left(-4\right)-17=-112-17=-129\)

\(-19-7.4=-19-28=-47\)

\(-14.\left(-2\right)-16=28-16=12\)

\(13.\left(-3\right)-65-4.\left(-6\right)=-39-65+24=-80\)

\(-24-8.\left(-6\right)+28=-24+48+28=52\)
