One of the most compelling Number Patterns in Mathematics is The Pascal's Triangle which is named after Blaise Pascal, a famous French Mathematician and Philosopher. To build the triangle, start with "1" at the top, then continue placing numbers below it in a triangular pattern. Each number is just the two numbers above it added together. The Binomial Theorem is a quick way of multiply out a binomial expression that has been raised to some (generally inconveniently large) power. For instance, t

Exponential growth or decay can be modeled using an exponential function of the form: y = P ( a) ^x P = initial value of y x = time or any value for x a = multiplication factor If then the function y is an exponential decay where a = 1 - r and r is the decay rate as a decimal number. This document discusses applied problems that relate to exponential growth or decay. The ideas have been laid out so that they are easy to follow. Questions and answers are given. Step by step solutions are a
