Currently this bot has only one function: /solve. This
command takes one argument that is a mathematical expression of quadratic equation. For example /solve x^2 - y^2 + 1 = 0. After a command is fired a
request is sent to Wolfram Alpha API with a response of huge JSON containing detailed answer of question
provided such as real solution, graphical plot, etc. Currently the bot will respond with ‘real solution’ and
‘grapichal plot’ for each question.

This bot uses free Wolfram APPID, so it can’t fire more than 2000 API requests per month.
The version that I submitted to Cloudflare Summer Challenge is implemented using Cloudflare Workers inside the javascript runtime with no 3rd-party library
