$2\sqrt{12}$-$3\sqrt{48}$=$4\sqrt{3}$-$12\sqrt{3}$= -$8\sqrt{3}$

$-3\sqrt{18}$+$2\sqrt{8}$= -$9\sqrt{2}$+$4\sqrt{2}$= -$5\sqrt{2}$

-$2\sqrt{24}$-$3\sqrt{54}$ = -$4\sqrt{6}$-$9\sqrt{6}$= -$13\sqrt{6}$

$3\sqrt{20}$-$4\sqrt{45}$=$6\sqrt{5}$-$12\sqrt{5}$= -$6\sqrt{5}$

$2\sqrt{24}$-$3\sqrt{6}$=$4\sqrt{6}$-$3\sqrt{6}$=$\sqrt{6}$

$5\sqrt{10}$-$4\sqrt{40}$=$5\sqrt{10}$-$8\sqrt{10}$= -$3\sqrt{10}$
