in say, physics theres alot of expectation for you to know what symbol means what, but in terms of just general algebra, yeah variables are represented by letters and, variables change, and as such the letters to represent them change
I was gonna bring up the physics thing
if there's ever two letters/symbols that mean different things, the TYPE of problem and the other units are the giveaway as to what the variable is referring to (im a physics nerd :D)
ie k=(1/2)*mv^2 (kinetic energy formula) vs k=R/N (Boltzmann constant)
and other times it just comes down to strict memorization of formulas =o
but if all else fails...write the answers on your hand >_>
well i can say in all honesty, i remember no specific equations from physics class, lol, it was awhile ago. but as for the memorization, its easier when you have to do it, lets look at those two equations ya wrote, no one probably knows what the letters mean specifically, but, both are motion formulas, and both start k= so, yeah, you get what i mean there, by process of elimination once you know a few equations you should be able to take stabs in the dark as to what random formulas could possibly pertain to
