Tedious? not quite, let’s jump in and see how Symbolab can help you solve matrices.

To start with we’ve added easy to use buttons to type in matrices; this is how it looks like:

Matrices of the same size can be added or subtracted element by element.

Here’s an example (click here):

Not too complicated, just takes a lot of work

Two matrices can be multiplied only when the number of columns in the first equals the number of rows in the second. If A is an m-by-n matrix and B is an n-by-p matrix, then their matrix product AB is the m-by-p matrix whose entries are given by dot product of the corresponding row of A and the corresponding column of B.

To make this simple, let’s take a look at an example (click here):

Multiplying matrices is no fun…

To transpose a matrix simply swap the rows and columns

Here’s an example (click here):

The trace of an n-by-n square matrix is defined to be the sum of the elements on the main diagonal
