I was trying to design some GUI for a tool I'm making and I noticed there's a hidden math problem somewhere in there. Not being one to let the opportunity slide, I decided it's worth exploring. Basically there's 3 buttons that add to a variable. What are the best values to put on those buttons so any number up to 100 can be made with the least amount of clicks. Only I don't know how to approach this systematically. Best I got is intuition at this point. Or the brute-force approach.
