Most of us have heard of Fibonacci numbers and know a little about what they are, but what about N-bonacci numbers? In this article we will look at what they are and how they link to the Fibonacci sequence.

The world of Trigonometry is based on the Unit Circle and the relationship between two of the Circle's infinite number of radii. This relationship is expressed fundamentally as the SIN and the COSINE of the angle formed between the two radii.

Subtraction is just the inverse of addition. To subtract integers, you just have to change the subtraction problem into an addition problem, then perform the "Keep, Change, Change" method.

To add integers using the number line, always start at zero and move n units to the right if the number is positive and n units to the left if the number is negative.

Few people would have predicted the mathematical controversy that would follow the first time the 'three door problem' was played on the quiz show, Let's Make A Deal. The game is easy to play, but the implications in terms of probability theory were controversial and divisive.

An enthusiastic teacher goes overboard to discuss the famous Pancake Problem, bringing in sorting algorithms and recursion techniques in an analysis of stacks of different sized pancakes. Intuitive conclusions are drawn regarding the number of pancake tosses a hapless chef needs to make.

The area of a flat shape can be estimated by dividing it into unit squares and counting their number. Pick's Theorem provides a method to find the exact area of a polygon drawn on a dotted grid. We look at how the Theorem works and establish a proof using Euler's formula.

Shaking hands is one of the most common activities we do. But have you considered just how many handshakes you would have to make in a room full of people? We will delve into the mathematics of handshaking and combinatorial analysis.

This mathematical investigation generally aimed to develop a mathematical formula to calculate the number of regions formed by connecting the points on the perimeter of a circle. Specifically, this investigation aimed to observe some patterns that will help the investigator develop a conjecture.

A casual summer job with a motley crew of tradesmen almost made me regret that I wasn't back at University. This was until I came to understand their special brand of humour, knowledge and their worship of Pythagoras.

Mathematical language is a system used to express, communicate and convey mathematical information. It is distinct and unique from the usual language that people are used to and is used to communicate abstract and logical ideas. Mathematical language is characterized by abstraction symbols and rule.

Fibonacci Sequence is popularized in Europe by Leonardo of Pisa, famously known as Leonardo Fibonacci. The nth term of a Fibonacci sequence is found by adding up the two Fibonacci numbers before it. But how can we find the nth term of a Fibonacci sequence without it's two preceding terms?
