Hello, I'm new here and I would like to introduce you with my hobby. I created some interesting quizzes and I think that would be interesting to this community. Well I creating quizzes from many different topics and also quick math quizzes. I give you 10 questions and you must answer on it for a less then a minute. It's pretty hard so if you interested you can try it on math quizzes
Welcome to the forum! Thanks for providing that.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.
