hexadecimal-practice

CLI application for practicing hexadecimal math (e.g. addition)

This was built to make hexadecimal numbers more familiar to work with.

npm install -g hexadecimal-practice

The program can be run via:

Documentation

CLI

We provide an executable hexadecimal-practice upon installing hexadecimal-practice. The options can be found via --help:

$ hexadecimal-practice --help

  Usage: hexadecimal-practice [options]

  Options:

    -h, --help                 output usage information
    -V, --version              output the version number
    --seed <seed>              Specify a seed to use for number generation
    --maximum-digits <digits>  Specify the maximum amount of digits to use (hexadecimal base)

Examples

Digits

For hexadecimal novices, 2 digit numbers can be overwhelming. By using --maximum-digits 1, we are prompted with single digit hexadecimal numbers:

$ hexadecimal-practice --maximum-digits 1
What is the answer for: 4 + d? 11
What is the answer for: 6 + 8?
