## VIDEO: Algebra Applications: Variables and Equations |
In this episode of Algebra Applications, two real-world explorations are developed: Biology. Analyzing statistics from honey bee production allows for a mathematical analysis of the so-called Colony Collapse Disorder. Geology. Why do rivers meander instead of traveling in a straight line? In this segment the geological forces that account for a river’s motion are explained. |
Applications of Equations and Inequalities, Variables and Unknowns, Variable Expressions | |

## VIDEO: Algebra Applications: Variables and Equations, Segment 1: Introduction. |
An overview of the key topics to be covered in the video. This video includes a Video Transcript: https://www.media4math.com/library/video-transcript-algebra-application… |

## VIDEO: Algebra Applications: Variables and Equations, Segment 2: Honey Production. |
Honey bees not only produce a tasty treat, they also help pollinate flowering plants that provide much of the food throughout the world. So, when in 2006 bee colonies started dying out, scientists recognized a serious problem. Analyzing statistics from honey bee production allows for a mathematical analysis of the so-called Colony Collapse Disorder. |

## VIDEO: Algebra Applications: Variables and Equations, Segment 3: River Ratios. |
Why do rivers meander instead of traveling in a straight line? In going from point A to point B, why should a river take the circuitous route it does instead of a direct path? Furthermore, what information can the ratio of the river’s length to its straight-line distance tell us? In this segment the geological forces that account for a river’s motion are explained. |

## VIDEO: Algebra Nspirations: Variables and Equations |
Ever since the mathematics of the Babylonians, equations have played a central role in the development of algebra. Written and hosted by internationally acclaimed mathematics educator Dr. Monica Neagoy, this video traces the history and evolution of equations. It explores the two principal equations encountered in an introductory algebra course – linear and quadratic – in an engaging way. |
