MDH - Mathdh — Mathematics Drills with Haskell

You know… It kind of sucks how we all forget everything we learned in school.

One of the worst things is certainly math. I mean, we spend all this time learning it, just to have it slowly dissipate in the background. But with just a slight investment of time, we can keep our skills tip top. So…

That's why I made this. It also has helped me a lot with my arithmetic in general, I used to be almost unable to calculate anything in my head, but with the help of daily drills in mhd, now I can almost calculate my groceries while shopping… Or well not really, but I can do multiplication pretty darn fast!

I just was annoyed that I had this program siloed in the depths for my random code projects folder where it just collected dust. So here! Perhaps I'll even give it some love when time permits.

Features

  • Addition, Subtractions, Multiplication, Division problems.
  • Practice multiplication tables (or other types of table operations).
  • Drill random combinations in a range you find comfortable.
  • Super simple and fast, making it a very eacy habit to put into those gabs in your workday. E.g. could be run every time you log in quizzing you with just 5 random questions.
  • Super lightweight.

Manual

The program has been developed on NixOS for now the only supported way to run it is on NixOS.

Downloading

git HTTPS

To get the latest version with git over HTTPS:

git clone https://github.com/cafkafk/mathdh.git

git SSH

To get the latest version with git over SSH:

git clone git@github.com:cafkafk/mathdh.git

Building

Linux - NixOS

Compiling

Navigate to your local copy of the repository. When you're in the root directory, simply run:

./build.sh

And the binary will be built for you in the local directory and installed in your nix user profile.

Usage

To use mdh, just run:

mdh

Which will produce no output beyond telling you that the program is done.

However, using a command like:

mdh 11 1 10 "*" +

Will start a drill session where you go through the operations * and +, starting with a refresher of all the combinations from 1 to 10, before giving you 11 random questions per number in the range you gave, with another number in the same range.
