How do you multiply two numbers together? Through a process of addition and
bit shifting (the second is optional if you are willing to wait a long time
for the result). How do you compute a power? By multiplying (or by
computing a logarithm or two).
All these esoteric mathematical operations are expansions of addition and
bit shifting.
