=7.2+[2−{0.3−0.8}]  =7.2+[2+0.5]  =7.2+2.5  =9.7
$$=\mathrm{7}.\mathrm{2}+\left[\mathrm{2}−\left\{\mathrm{0}.\mathrm{3}−\mathrm{0}.\mathrm{8}\right\}\right] \\ $$$$=\mathrm{7}.\mathrm{2}+\left[\mathrm{2}+\mathrm{0}.\mathrm{5}\right] \\ $$$$=\mathrm{7}.\mathrm{2}+\mathrm{2}.\mathrm{5} \\ $$$$=\mathrm{9}.\mathrm{7} \\ $$
