Answer 2

`\bf 12.6(2-3)+2^6 / 4\implies \stackrel{\mathbb{P~E~M~D~A~S}}{12.6(\stackrel{\stackrel{2-3}{\downarrow }}{-1})}+2^6/ 4\implies 12.6(-1)+\stackrel{\stackrel{2^6}{\downarrow }}{64}/ 4 \\\\\\ \stackrel{\stackrel{12.6(-1)}{\downarrow }}{-12.6}+64/ 4\implies -12.6+\stackrel{\stackrel{64/ 4}{\downarrow }}{16}\implies \stackrel{\stackrel{-12.6+16}{\downarrow }}{3.4}`
