My wife teaches elementary-school math, and I’m somewhat of a math nerd, so the 24 game is right up our alley. Basically, you’re given four numbers, and you have to find a series of operations that makes 24 from those numbers. For example, given 1, 2, 3, and 4, you might respond that 1*2*3*4 = 24. Some sets of numbers are harder than others (much harder).
One day, my wife and her class were having trouble solving a particularly hard set, so she emailed me for help. It took me a while to find the answer, and all the while I was thinking to myself “Self, I’m a programmer. Why am I doing this the hard way?” So now I’ve created the easy (cheater) way. Go to http://jebware.com/24 input your 4 numbers, and it will tell you how to make 24.
