You can DO whatever the hell you want to do... nobody here will
convince you other than what you already think, so why bother asking
anyone here? If they say No, you'll disagree.. if they say yes,
you'll disagree.. save everyone the energy and just shut the hell up.

Time is running out(;^) I don't want to know much more algebra than I do
now. Thought I'd seek help here. Thanks for referring me to dimensional
analysis, but I've been able to cancel units for years:
Many years ago I overheard a H.S. algebra teacher tell his class _something
to the effect_ that the number one  was such that it didn't change the
value (of an equation) when it was inserted in an equation. That made a
lasting impression, since I didn't understand then, and don't now:
In particular: Writing that acceleration [a] is _inversely_ proportional to
the mass [m] of a body, as [a is proportional to 1/m]. That somehow doesn't
look 'copesthetic' to me; especially if 'm' is a variable.
I thought the rule might be simple enough for me to understand; but
apparently it's not,
