How do you multiply two matrices together?

To multiply two matrices together the inner dimensions of the matrices shoud match. For example, given two matrices A and B, where A is a m x p matrix and B is a p x n matrix, you can multiply them together to get a new m x n matrix C, where each element of C is the dot product of a row in A and a column in B.

What is matrix used for?

Matrices are often used to represent linear transformations, which are techniques for changing one set of data into another. Matrices can also be used to solve systems of linear equations

In math, a matrix is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns.

How do you add or subtract a matrix?

To add or subtract matrices, perform the corresponding operation on each element of the matrices. Note that in order to add or subtract matrices, the matrices must have the same dimensions.
