**Linear AlgebraÂ **is a matrix-based mathematical computation analysis. For many students, linear algebra can be a challenging subject that requires the right tools to expedite calculations, such as the Nickzom calculator.

According to Wikipedia, linear algebra is central to almost all areas of mathematics. For instance, linear algebra is fundamental in modern presentations of geometry, including for defining basic objects such asÂ lines,Â planes,Â andÂ rotations.

Also,Â functional analysisÂ may be basically viewed as the application of linear algebra to spaces of functions. Linear algebra is also used in most sciences andÂ engineering areas because it allowsÂ modeling many natural phenomena and efficiently computing with such models. ForÂ nonlinear systems, that cannot be modeled with linear algebra, linear algebra is often used as a first-order approximation.

### Sections You Can Solve with the Nickzom Calculator

Nickzom Calculator solves 8 major sections of Linear Algebra such as:

- Matrix Arithmetic

- Multiplication of Two Matrices
- Division of a Matrix by a Square Matrix

For the purpose of this post, I will love for us to find the inverse of a 3 by 3 square matrix.

First, you enter the number of rows in the matrix. In this case, it is **3**.

Next, you enter the matrix values according to rows in this format

Now click on calculate.

**Step 1**: It provides the determinant of the square matrix
