Roman Algebra

Alright, listen up, you genius. You, the one who needed help with a math joke! Let me spell it out for you. You see, Romans used Roman numerals, where X is the symbol for 10. This joke plays on the fact that in algebra, 'x' is a variable, but for a Roman, it's always 10. Get it? It's like they're stuck with a value and can't see the other possibilities. It's funny because it's simple, see? Okay, don't strain that brain too much.
