__Math Tutoring on Finding and Using Determinants__

A **Determinant** is a real number associated with a **square matrix****.** The **determinant** of a **square matrix A** is denoted by **"det A"** **or ****|A|.**** **

**Properties of Determinants:**** **

1) The **determinant** is not a matrix, it is a real number.

2) The **determinant** can be a negative number.

**3) **The **determinant** exists for square matrices only like **2 x 2, 3 x 3, ... n x n.**

4) The **inverse** of a **matrix** exists only if the **determinant** is not zero.

**Determinants** can be used to solve a linear system of equations. The method is called **Cramer's Rule****.**
