How to Multiply Matrices. A Matrix is an array of numbers: (This one has 2 Rows and 3 Columns) To multiply a matrix by a single number is easy: These are the calculations: We call the number ("2" in this case) a scalar, so this is called "scalar multiplication". Multiplying a Matrix by Another Matrix.
In mathematics, particularly in linear algebra, matrix multiplication is a binary operation that produces a matrix from two matrices. For matrix multiplication, the number of columns in the first matrix must be equal to the number of rows in the second matrix.
Matrix multiplication is the product of two matrices, which results in a single matrix. Visit BYJU’S to learn how to multiply two matrices, formulas, properties with many solved examples.
Here you can perform matrix multiplication with complex numbers online for free. After calculation you can multiply the result by another matrix right there!
When we multiply a matrix by a scalar (i.e., a single number) we simply multiply all the matrix's terms by that scalar. We can also multiply a matrix by another matrix, but this process is more complicated. Even so, it is very beautiful and interesting. Learn how to do it with this article.

OK, so how do we multiply two matrices? In order to multiply matrices, Step 1: Make sure that the the number of columns in the 1 st one equals the number of rows in the 2 nd one. (The pre-requisite to be able to multiply) Step 2: Multiply the elements of each row of the first matrix by the elements of each column in the second matrix.
