## The Euclidean Algorithm on the TI-84 Graphing Calculator

The Euclidean Algorithm an ancient Greek method for finding the greatest common divisor of two numbers. In spite of its age, it is still of great importance in modern mathematics and computing, for example in encryption algorithms such as RSA. There is a great video from James Tanton explaining the algorithm here. Below is TI-Basic […]

## The Jug Filling Problem on the TI-84 CE Graphing Calculator

The Jug filling Problem is a very interesting problem which can quickly take you into some fairly deep territory in the overlap between Maths and Computer Science. It is closely related to the Euclidean Algorithm, which is a method for finding the greatest common divisor of two numbers. (In the UK you might be more […]

## TI-84 CE Graphing Calculator & Little Man Computer

There is a great deal of potential for using the TI-84 CE Graphing Calculator for learning and teaching Computer Science. For example, many syllabuses require students to learn about assembly language. This is often taught using the now famous Little Man Computer – CPU Simulator made by Peter Higginson. This is a great tool to help […]

## The TI-84 Graphic Calculator

This picture is of the Texas Instruments TI-84 Calculator which I make a lot of use of in my teaching. It’s great for giving students dynamic representations of the concepts they are studying, as well as for playing interactive games which can be tailored to their particular needs. It can also be used to teach […]
