## What Is Matrix Division?

Matrix division, a term commonly used in linear algebra, is more complex than the name might suggest. In the realm of matrices, division is defined as multiplication by the inverse of a matrix.

Let's consider two matrices, $$$A$$$ and $$$B$$$. The division of the matrix $$$A$$$ by the matrix $$$B$$$, i.e., $$$\frac{A}{B}$$$ is equivalent to multiplying the matrix $$$A$$$ by the inverse of the matrix $$$B$$$, denoted as $$$B^{-1}$$$.

Mathematically, this can be represented as $$$\frac{A}{B}=AB^{-1}$$$.

The inverse of the matrix exists only if the matrix is square and invertible, i.e., its determinant is not equal to zero.

To provide a clearer understanding, let's take two 2x2 matrices:

$$A=\left[\begin{array}{cc}1&2\\3&4\end{array}\right]$$$$B=\left[\begin{array}{cc}5&6\\7&8\end{array}\right]$$To find $$$\frac{A}{B}$$$, we first need to find the inverse of $$$B$$$.

The formula to calculate the inverse of a 2x2 matrix is as follows: if $$$B=\left[\begin{array}{cc}a&b\\c&d\end{array}\right]$$$, then $$$B^{-1}=\left[\begin{array}{cc}\frac{d}{ad-bc}&-\frac{b}{ad-bc}\\-\frac{c}{ad-bc}&\frac{a}{ad-bc}\end{array}\right]$$$.

Using the formula above, $$$B^{-1}=\left[\begin{array}{cc}\frac{8}{5\cdot8-6\cdot7}&-\frac{6}{5\cdot8-6\cdot7}\\-\frac{7}{5\cdot8-6\cdot7}&\frac{5}{5\cdot8-6\cdot7}\end{array}\right]=\left[\begin{array}{cc}-4&3\\\frac{7}{2}&-\frac{5}{2}\end{array}\right]$$$.

Finally, multiply $$$A$$$ by $$$B^{-1}$$$: $$$\left[\begin{array}{cc}1&2\\3&4\end{array}\right]\cdot\left[\begin{array}{cc}-4&3\\\frac{7}{2}&-\frac{5}{2}\end{array}\right]=\left[\begin{array}{cc}3&-2\\2&-1\end{array}\right]$$$.

So, $$$\frac{A}{B}=\left[\begin{array}{cc}3&-2\\2&-1\end{array}\right]$$$.

This is how matrix division works. The process becomes more complex with matrices of higher dimensions, but the principle remains the same — multiply the first matrix by the inverse of the second.

## What Are the Rules of Matrix Division?

Matrix division is a relatively complex operation and is governed by a set of specific rules of linear algebra. Here are the key rules you need to remember:

**Existence of Inverse:**For matrix division to occur, the matrix acting as the divisor (the one being divided by) must possess an inverse, making it an invertible matrix. The existence of the inverse of a matrix depends on its determinant value. If the determinant of the matrix equals zero, it is classified as a singular matrix and doesn't have an inverse. Consequently, in such cases, matrix division becomes an impossible operation.**Multiplication by Inverse:**Matrix division is essentially the multiplication of the first matrix (the dividend) by the inverse of the second matrix (the divisor). In other words, if you are dividing a matrix $$$A$$$ by a matrix $$$B$$$, you multiply $$$A$$$ by the inverse of $$$B$$$.**Matrix Size:**The matrices involved in the division operation must be square matrices because only square matrices can have an inverse. Moreover, they should have the same dimensions.**Non-Commutativity:**Like regular number division, matrix division is not commutative. This means that $$$\frac{A}{B}$$$ is not equal to $$$\frac{B}{A}$$$.**Distributivity:**Matrix division is not distributive over matrix addition or subtraction. This means that $$$\frac{A}{B+C}$$$ is not equal to $$$\frac{A}{B}+\frac{A}{C}$$$.
