Almost integer

In recreational mathematics, an almost integer (or near-integer) is any number that is not an integer but is very close to one. Almost integers are considered interesting when they arise in some context in which they are unexpected. (Wikipedia).

What is infinity ?

Definition of infinity In this video, I define the concept of infinity (as used in analysis), and explain what it means for sup(S) to be infinity. In particular, the least upper bound property becomes very elegant to write down. Check out my real numbers playlist: https://www.youtube.co

Zero is an even number or odd number?

Is zero even or odd? Is it neither? Is it BOTH?!? Determining if zero is even requires that we know what it means for a number to be even. Even numbers are any numbers that are divisible by two. Meaning they divide by two without any remainder. This, in general, is what it means for one
