$$\left(\mathrm{2}\bigtriangleup\left(−\mathrm{3}\right)\right)\bigtriangleup\left(\left(\left(−\mathrm{2}\right)\bigtriangleup\left(−\mathrm{1}\right)\right)\right. \\ $$$$=\left(\mathrm{2}^{\mathrm{2}} +\left(−\mathrm{3}\right)\right)\bigtriangleup\left(\:\left(−\mathrm{2}\right)−\mathrm{2}\left(−\mathrm{1}\right)\right) \\ $$$$=\mathrm{1}\bigtriangleup\mathrm{0} \\ $$$$=\mathrm{1}^{\mathrm{2}} +\mathrm{0} \\ $$$$=\mathrm{1} \\ $$
