Almost forgot to post today! X is a commonly used stand in for numbers in math. According to some, Descartes is the reason why. He introduced it in one of his many works, and he had been using it years before.
This is a very short post because I have to run, I have a math thing to go to. But I want to use the last three days to do varibles in math because it's a light and easy way to end this intense moth. Also, I have a project I'm working on that needs care and attention.
