April 11, 2018: Seven Years

April 11, 2018:  Seven Years

The blog is officially 7 years old! I love mathematics and this blog has one way of expressing that passion. 

It wouldn’t be the success that it is without you, your comments, and your support. Thank you so much‼!

By the way, I also added a file below, which is a collection of some mathematical formulas and refines including:

* Geometry
* Trigonometry
* Basic Finance
* Calculus
* Differential Equations
* Statistics – Linear Regression
* Quadratic and Cubic Equations
* Constants and Solar System Data

Why did I use a large font?  My aim is to create a reference that would fit and be readable, even on Android or iPhone smartphones.  This is a quick reference that can be used off line.  If you download the PDF file, I hope you enjoy this and find it helpful.

Here’s to another year!



  1. A Very Happy 7th Blogversersary!

    Thanks for the great resource. I often find I spend too much time looking for formulas I have not used in some time and your file will be put to good use.

    1. Thank you Bill! Glad it will be of use.

      Here's to many more years of blogging,
