No; it's my anecdotal observation that many non-math, non-science folks don't like to type the little upper-case exponents for alliterating names (or acronyms), like, say, Ann Arbor, which gets written as A2 but spoken as A-squared. Sometimes the number migrates to the front of the expression. Ergo, plausibly, the progression: MM, M^2, 2M, in the vernacular.

In fact, G (giga) for billion and T (tera) for trillion.
