Zero factorial DOES NOT equal 1 - Explained!
How you been told that zero factorial equals one (0! = 1)? If you did, then stop and watch this video! In it I show why explanations for this are either flawed or JUST PLAIN WRONG! Come see how to think of what zero factorial equals! Videos explaining factorials sometimes explain why zero factorial is 1 (for example, numberphile) either use explanations that don't really prove what zero factorial equals, or give "proofs" which are incorrect. In this video I go through these explanations in detail. I also show exactly how to think of zero factorial (0!).
