Factorials
Today in Mathland we learned about sequences and factorial a. My favorite was the factorials! They are so neat. You take a number and multiply it with all the numbers that come before it. So if you have 4! you multiply 4x3x2x1. And you get 24. You can also divide and multiply factorials together. That's when it gets really fun. I can't wait for a quiz on factorials!

Thanks for the example, it really does show how to solve problems with factorials. I also agree that factorials are pretty cool. I also like it when I get to divide factorials when the top number and the number in the denominator are really close together! All you need to do then is just cross numbers out!
