What would happen if you mixed a math education tutoring site with a late night 900 number?
Well, someone did, and it might end up being one of the strangest new startups out of Cambridge. It's called SolveX4U.com.
While this might look like a silly idea it's been gaining a lot of traction in the past week and the tech behind it is actually pretty advanced and useful for students who are looking for help with math, statistics and other subjects.
Anyone can submit any math problem and they will get help solving it (the first one is free too).
