If the calculator displays a dimension mismatch, remind the students to check the dimensions of their matrices before computing sums or products. Discuss how multiplying matrices is different from adding or subtracting matrices. What are the criteria for when two matrices can be added or subtracted?

Jan 20, 2009 · We have defined operations for adding, subtracting and multiplying matrices. Matrix inversion is the matrix analog of division. For a square matrix, A, we define a matrix inverse, A-1, by the following equation. [48] If we have a matrix equation, Ax = b, we can, in principle, solve this equation by premultiplying both sides of the equation by A-1.

Hint: refer to Equation 1 to see if you need to use identity matrices of different dimensions to calculate the product IA, IB, and IC. Matrix Division In terms of the way we usually think of division of numbers or functions, i.e., or , matrix division () isn’t defined.

Discuss with students the dimensions of the matrices. (Both matrices are 4 ( 3 matrices because they have 4 rows and 3 columns) Tell students that each matrix can be identified using its dimensions (i.e.,). Provide examples of additional matrices for students to name using the dimensions.
