My friend and I have been trying to solve this for literally years and we are stuck. Does any one have any ideas? We have tried using a computer program but all of our algorithms are much too slow. Essentially, use numbers 1-36 each only once. We are unsure if order of operations matter or not but we assume they do. Any help would be appreciated!! submitted by /u/katesblue99 [visit reddit] [comments ..read more

Say you have a randomly shuffled deck of cards. You can look at the top two cards of the deck, and choose whether to put any at the bottom, any at the top and in what order (think scrying like in MTG). By repeating this process indefinitely, can you stack the deck so that it is arranged in any way you’d like? submitted by /u/Odd_Discussion9928 [visit reddit] [comments ..read more

This world is a world of swords and magic. In the trained Royal Guard of the Kingdom of Fantasia, 90% are masters in archery, 80% in swordsmanship, 70% in black magic, and 60% in white magic. No one has master-level skills in all four categories: archery, swordsmanship, black magic, and white magic. What percentage of people are neither masters of black magic nor white magic? submitted by /u/st4rdus2 [visit reddit] [comments ..read more

I saw this puzzle in an old book with math games. The objective of the puzzle is to get rid of a six digit number if four moves so that calculator will read 0. You start with a six digit number with all digits being different. And you can use two digit numbers and any of +-*/ operations. Example in the book, you start with 542681. In the first move you subtract 81 to get 542600, then divide by 50 to get 10852, then divide by 52 to get 208.6923 and final move by dividing with 99, resulting in 2.10800. And it says that the move 3 was wrong and as result we lost this round. There is a claim in t ..read more

Hello, I use critically acclaimed software for my fantasy football drafts that helps me identify the best value at each pick. The software generates projections for each player, including their floor, average, and ceiling, based on various factors. While this usually works well for most leagues and their scoring settings, one league I'm in has two specific factors that lead to slightly different scoring. As a result, I need to revise the player rankings by factoring in the likelihood of these two types of factors occurring for particular players prior to the NFL season. From my basic understa ..read more

I can't figure this out for some reason and I'm usually good at math. Here it is: "A sum of money is to be divided among Gurdeep, Jade, and Quarren. Gurdeep receives one-third of the entire sum plus $8. Jade then receives two-fifths of what remains plus $7. Quarren receives the rest, which amounts to $293. How much did Gurdeep and Jade each receive?" Show your work and let's see what you got! submitted by /u/rodine14 [visit reddit] [comments ..read more

I think this is a math puzzle. I don't know the answer (I haven't tried to work it out yet). I'm hoping the puzzlers here can find the answer for me! Every year we interview about 6 students for a set of scholarships. There may be anywhere from 1 to 6 scholarships awarded. The scholarships are awarded after the interview weekend. How many group photos (i.e. including all 6 candidates), in what arrangements, do we need to take to be sure we have a photo that includes all the final recipients standing in line? (e.g. if candidates B,C and D got scholarships, we could use a photo by cropping out ..read more
