The Clock Arithmetic and Modular Systems Series

September 4, 2012 GB High School Mathematics, High School Number Theory

This is a series of posts that explains modular systems starting from an intuitive introduction using clocks. I wrote this for high school students of average mathematical ability.

I hope you find the series easy to read and student friendly.

The Series

Part 1: Introduction to Clock Arithmetic and Modular Systems

This post introduces modular arithmetic intuitively using the 12-hour clock mathematical operations. What happens if we add the numbers on the clock? » Read more

Mathematics in Microsoft Office

August 25, 2010 GB Teaching Tools

There are many people who are allergic with mathematics, but most of the time, mathematics appears incognito in places where we don’t expect them to be. One perfect example is the Microsoft Office Package.We know the MS Excel is dedicated to mathematical computations, but what about MS Word or PowerPoint? Can we find mathematics in both applications?

Enumerated below are the mathematics hidden in Microsoft Office. Regarding the mathematics found in MS Excel, we will discuss more about them in later tutorials.

1. Equations (Word). In the Insert menu of MS Word, you can see the Equation icon located at the extreme right hand side of the toolbar. This contains several built-in mathematical equations and formulas such as area of the circle and binomial theorem.
