"A formal manipulator in mathematics often experiences the
discomforting feeling that his pencil surpasses him in intelligence."

Howard Eves

Write down your equations with Math-o-mir, the mathematical notepad.

The idea behind Math-o-mir was: "why can't I use my PC as simple as I am using pencil when writing mathematical equations?"

What is Math-o-mir

The Math-o-mir is a software tool designed to write and edit mathematical equations as easily as possible. The goal was to achieve the same level of simplicity as with pencil and a sheet of paper. It is designed to act as your personal math notepad where you can write down your quick and informal calculations.
  • engineers use it instead of a scrap paper to quickly write down calculations and ideas
  • students use it to write down lesson notes directly on their computers
  • teachers use it to prepare and publish teaching materials or even exams, all in electronic form
  • well-informed people use it as an easier and quicker way to generate equation images and insert them into text documents
In Math-o-mir you can touch expressions and expression elements and then, by mouse click, copy them around your mathematical document and insert them into other equations. You can also make simple hand-drawings to illustrate your equations...
  • or edit math equations lazily with your mouse or efficintly using your keyboard
  • or export your work as a raster image or LaTeX code
  • or plot and analyze funcitons
  • zoom, scroll, print, "and do the other things"...
Simple symbolic calculator is embedded to assist you with 'boring' stuff. This makes Math-o-mir a basic CAS tool.

If you are math teacher, you may consider using Math-o-mir in your classroom.

There is also this page where I explain the two most important aspects when dealing with the Math-o-mir. In addition, I also created this Math-o-mir blog where you can work with me on Math-o-mir development by providing useful comments.


The downloadable video clip shows how can you edit equations by mouse (.wmv 1.5M). (Sorry, the quality is very low because my bandwidth is very limited).

There are few third-party videos, like this one.
