Reducing a 4 digits numbers to a 2 digits number ?
Hi everyone, I don't think that is possible but I'm gone ask anyway. How can you reduce a 4-digit number into a 2-digit number using every possible method, while also ensuring that you can trace back to the original 4-digit number? List all possible ways to do this, such that the transformation is reversible and allows recovery of the original number. I forgot to mention that I work on Excel 2007. Thank you.

Geometric Analysis in predicting next drawing range
Good Morning Team, Was reviewing the analysis of last nights PB results (graphically in excel), and wondered if there may be any predictive value in analyzing the change from drawings, that may predict the amount of change for the next drawing. As an example (since visuals are so much more explanatory): The analysis I am referring to is essentially assessing the change of distance of the hypotenuse, when considering the first vertical change (solid black line) is 8 (58-50), and the s

Tell A.I to explain so that a fifth grader could understand. We all will be able to grasp the narrative. lakerben Nov 25, 2011, 12:05 pm Quote: Originally posted by on Nov 24, 2011 example 139 becomes delta 26. How? between 1 and 3 has 2 spaces, and between 3 and 9 there is 6 spaces. so we have 26 Easier to track. If we want to convert back, we will have 10 combos to play every possible 26. Example 26= 028-139-240-351-462-573-684-795-806-917 Mak

Time for a Pop QuizReply
I think I got this. I can't think of a less difficult way. To get at least 14 questions right, Beavis has to get 14, 15, 16, 17, 18 or 20 questions right. He can't get 19 questions right because getting 19 of 20 right means the 20th question must be right. There are 20! different ways to arrange the 20 unique answers. 20!=20*19*18*...*3*2*1=a huge number, approximately 2.4 million times a trillion. Only one of those ways results in getting all 20 questions right. To get 18 right and
