### Defining MDETERM and its Purpose

**MDETERM is an Excel formula.**

It calculates the determinant of a matrix. That determinant number gives info on the matrix, like if it is *invertible* or *singular*.

MDETERM makes it easier to calculate determinants without having to use complex algebra and fractions.

The syntax for using MDETERM is **“=MDETERM(matrix)”**, where matrix is your selected range containing the target matrix numbers. This will return the value of the determinant for that range.

To find out if a square matrix can be inverted, use MDETERM. If the determinant is 0, it can’t be inverted. Otherwise, you can use MINVERSE to invert it.

### Syntax and How to Use MDETERM

Start by selecting the cell where you want the result to appear.

Type ‘**=**‘ followed by ‘**MDETERM(**‘ to begin using the formula.

Inside the parentheses, enter a range of cells containing a square matrix or an array constant.

**MDETERM** is used to calculate the **determinant of a matrix**.

It’s a scalar value used for linear algebra and calculus.

Let’s look at the syntax:

‘**=MDETERM**‘ followed by the matrix or array constant.

Helpful tips include:

- Keeping matrices well-organized and formatted.
- Double-checking input range before running the formula.

Now, let’s delve further into Excel’s **MDETERM**.
