Ah, I see you're curious about algebra, friend. Expressions that use a letter to represent an unknown quantity are called variables. They help us solve problems and equations by giving us a way to work with unknown values in a clear and organized manner. Just like adding colors to a painting, variables add depth and meaning to mathematical expressions.
