I had a rocky start with algebra in the 8th grade. The teacher said unknown constants are represented by lower case letters from the beginning of the alphabet while unknown variables are represented by lower case letters from the end of the alphabet. He gave an example with something like ax-b=0. Solving for x we get x=b/a. I asked why x is a variable and a and b are constants. If you fix the values of a and b, you also fix the value of x. I don't remember his exact answer, but it was something like you're given a and b and solving for x. For some reason, I had a problem with that.
