True^^^. But i cant seem to figure out how some of the stuff works. Like the equation solver. And a few other parts of the program dont work for me. But i think maybe i just need to redownload it.

Its great though. I used it for like 10 problems today. It’s especially good for distance, slope, and midpt. does it in 3 seconds.
