25. Matrix Operations

Using three settings students apply matrix addition and multiplication. Statistics of recent NFL quarterbacks from several years allow students to see the definition of matrix addition, matrix subtraction, and scalar multiplication. Using a problem setting from Contemporary Precalculus through Applications students investigate orders of students at a lunch counter using a probability, the transition matrix, and matrix multiplication. A similar technique is used to investigate the location of a mouse in a maze as a follow-up activity

Technology: PowerPoint slideshow for NFL problem, animation for mouse in the maze problem, graphing calculator.
