MM? Using roman numerals... Seriously, I do value good notation, but for this particular case, juxtaposition, we do use it for multiplication - in algebra, where it's easy to find the boundary of a number, and variables are always 1 symbol long, so 'xyz' is a product of three values, not a name of one.
Coming back - notation is important, but sometimes it's hard to find "the best" or even "good enough". Newton's primes as symbols of differentiation used alongside with Leibniz' dy/dx, and there is the shortcut for "differentiated by time" as dot on top of the function symbol, so for various cases different notation is more convenient.
I guess that the "Combining Cyrillic Ten Millions Sign" could do the job: ꙰ ꙰
Though you point it seems is more like using only a small set of symbols. Obviously, to render large number you need to introduce new syntax apparatus if keeping terseness is a desired constraint.
Just like you would wrote 1×10⁷ or 1e7, you can have say a single point on one line, and an heptagon or seven points on an other, still juxtaposing these two columned digits. In Unicode, it seems these last symbols are not present, but instead you can use cards from different games.

Ok, now do a million plus a million.

MM in Roman numerals is 2,000. There are some Unicode symbols representing one million, but I dunno if they're in the range HN accepts.
oo
Now do ten million plus ten million

How fun! :D
