This program can accomplish tasks such as addition, subtraction and multiplication of matrices along with finding determinants and inverses of a matrix. May be pretty helplful in online classes to calculate on the fly. It can calculate ~85 % of NCERT questions. Trust me, I myself have used this in my math class and the teacher was really impressed.

6. Inverse matrix
0. Exit
Your choice: > 3
Enter size of first matrix: > 3 3
Enter first matrix: 
> 1 7 7
> 6 6 4
> 4 2 1
Enter size of second matrix: > 3 3
Enter second matrix: 
> 3 2 4
> 5 5 9
> 8 0 10
The result is: 
94 37 137
80 42 118

1. Finding inverse of a really complex matrix to show how cool this is.
   • Answer is correct. I checked on Wolfram-Alpha :-)

The code may (most certainly) have bugs. Please feel free to open up an issue describing how I messed up (in a polite way please.)
