Dude, @Sanchayapol Lewgasamsarn that was the most boss collection of problems I've ever seen on this site! Awesome! I solved all of them until 7, and then missed each one after that. They were still insanely fun to solve and excellent practice. @Calvin Lin you need to see this! :O

Nice set! I really liked to go through and refresh my memory of number theory and mods. However, #9 and #10 were a little too easy to guess. :P
