Why can I have more than two 2!'s when Im dividing a #? Ex. 26800/(2!)(2!)(2!) <- Wont let me add the third 2!
It only likes one implied multiplication. You have to enter it as 26800/(2!)(2!*2!)
If you are using the key labeled "nPr", it only takes TWO parameters. Example: nPr(52, 5), which means this: 52P5= 52 x 51 x 50 x 49 x 48 = 52! / (52 -5)! = 311,875,200
