Really fun, nice game! 4/6 easy, 19.1s 47/77 medium, 16.2s 19/25 hard, 17.8s I started scribbling numbers on paper without looking down when I got to the hard ones, which helped...but I still think the hard ones were slightly easier than medium ones. Good question design: forcing you to look ahead simplify things like 69 * 2 - 5 / 7 ... realizing that 69 is one smaller away from being evenly divisible by 7, when doubled is 2 smaller, minus 5 makes it 7 smaller so the divided by 7 can apply to the thing it's close to...140 as well as the 7 smaller..140/7 minus 1...19 Common core on steroids?
