## IM Commentary

1. $$4+1=5 \hskip4em 5 = 4+1$$ $$1+4=5 \hskip4em 5 = 1+4$$ $$5-4=1 \hskip4em 1=5-4$$ $$5-1=4 \hskip4em 4=5-1$$
2. $$3+5=8 \hskip4em 8 = 3+5$$ $$5+3=8 \hskip4em 8 = 5+3$$ $$8-3=5 \hskip4em 5=8-3$$ $$8-5=3 \hskip4em 3=8-5$$
3. $$4+4=8 \hskip4em 8 = 4+4$$ $$8-4=4 \hskip4em 4=8-4$$
4. $$4+5=9 \hskip4em 9 = 4+5$$ $$5+4=9 \hskip4em 9 = 5+4$$ $$9-4=5 \hskip4em 5=9-4$$ $$9-5=4 \hskip4em 4=9-5$$
