## What is the determinant in a matrix?

The determinant of a matrix is the scalar value or number calculated using a square matrix. The square matrix could be 2×2, 3×3, 4×4, or any type, such as n × n, where the number of column and rows are equal.

## What is determinants with examples?

The definition of a determinant is something that determines an outcome or result of something. When your boss’ opinion is ultimately the only opinion that matters in making a decision in your office, this is an example of a determinant.

What is the determinant of a 2 by 3 matrix?
