What is a pro-numeral?

Answer 1

Oh, dude, a pro-numeral is just a fancy way of saying a variable in math. It's like when you're too lazy to figure out the exact number, so you just use a letter instead. So, instead of saying "x equals 5," you can be all cool and say "x is a pro-numeral." It's like math's way of being mysterious and chill at the same time.

Answer 2

A pro-numeral or pronumeral is another term for a variable in algebra. For example in the term 2x the x is the pronumeral or variable.
