Matrix $\mathbf{A}$ can be multiplied by matrix $\mathbf{B}$ if the number of rows of matrix $\mathbf{B}$ is equal to number of columns of matrix $\mathbf{A}$.

Then their product is: $$ \mathbf{a} \cdot \mathbf{b} = \begin{bmatrix} a_{1} & a_{2} & a_{3} & \ldots & a_{n} \end{bmatrix} \cdot \begin{bmatrix} b_{1} \\ b_{2} \\ b_{3} \\ \vdots \\ b_{n} \end{bmatrix} = a_{1}b_{1} +a_{2}b_{2} + a_{3}b_{3} + \ldots + a_{n}b_{n},$$, $$\begin{bmatrix} 2 & 4 & -1 & 3 \end{bmatrix} \cdot \begin{bmatrix} -1 \\ 6 \\ -2 \\ 0 \end{bmatrix} = 2 \cdot (-1) + 4\cdot 6 + (-1) \cdot (-2) + 3 \cdot 0 = -2 + 24 +2 +0 = 24. Multiplication of matrices is not commutative, as we can see from the previous example. that is, the addition of matrices is associative. This means that every element of a matrix $\mathbf{A}$ is multiplied by $\alpha$. Students will practice the addition, subtraction, and scalar multiplication of matrices ranging in dimension from 1 to 4.
The following properties are valid for the multiplication of matrices (if the specified products are well defined): Necessary cookies are absolutely essential for the website to function properly.
