# Description

This free app is a math calculator, which is able to calculate the determinant of a matrix. The determinants of following matrices are available:

- 2x2 matrices

- 3x3 matrices

- 4x4 matrices

- 5x5 matrices

- nxn matrices (with more than 5 rows and columns)

Best math tool for school and college! If you are a student, it will helps you to learn!

Note: In linear algebra, the determinant is a value associated with a square matrix. The determinant provides important information when the matrix is that of the coefficients of a system of linear equations, or when it corresponds to a linear transformation of a vector space.

Very good . Buggy... Very helpful app. Would request a dedicated button to refresh all the values to 0. And also better UI. The ads are annoying at top. Put em in the bottom. Will give 5 stars if all the above are fixed.

thanks GK Apps April 7, 2014

i will make it soon GK Apps November 4, 2013

can you give me an example of the determinants. i want to investigate this. Poor Serious Lag when opening and ask for fine GPS location? Why?

Plz improve It always creates force close before we solve. So plz improve it
