What is 1x2x3x4x5x6x7x8x9x10?

Oh, dude, you're hitting me with some math here. Okay, so when you multiply 1x2x3x4x5x6x7x8x9x10, you get 3628800. It's like when you're trying to figure out how many slices of Pizza you can eat in one sitting - you gotta do the math to make sure you don't overdo it, you know?
