AI assistant platform


To come (Oct. 3, 2025)

Here is the preliminary version (you do need a pen or a mouth that can be used to write on the screen, finger writing on my android phone also works):
  • If you want to practice on fraction, use frac@gmail.com and password 2025 to log in;
  • If you want to learn how to solve a parametric equation (like: solve ax=1 for x), use para@gmail.com and password 2025 to log in;
  • If you want to learn how to solve all kinds of quadratic equations (like: solve x^2=3/4+i for x), use quad@gmail.com and password 2026 to log in.
  • You can also try some Calc III questions. Here are some questions on series: CalS26-1@ou.edu(PSW 20261); CalS26-2@ou.edu(PSW 20262); CalS26-3@ou.edu(PSW 20263); CalS26-4@ou.edu(PSW 20264).

    • AlgeCal --- Calculator for learning Algebra (calculator that shows steps)

    Whether we agree or not, we cannot stop students from using calculators. Instead, we can improve them. What if we redesigned calculators to show intermediate steps, handle negative coefficients, and connect decimal operations with polynomial operations?
    Here is our contribution: AlgeCal — a calculator designed to prepare students for learning algebra.

  • Manual for using the calculator.


    • More detail about the calculator can be found in our book.
