Square Matrix Calculator
Calculate the determinant, the rank and the inverse of and square matrices.
Add, subtract, multiply matrices and matrices by a scalar.
Choose an operation from the list, select the size of your matrix and enter the elements. Press SOLVE to calculate the result.
Use the app to check your calculations and discover some fundamental properties of matrix operations.
Ready, Set, Practice!
Create an example of matrix addition in the app, to discover how to add two matrices. In general, you can add matrices only when they have the same size (they must not necessarily be square matrices, then!). Calculate:
Calculate the determinant of the matrix: Is this matrix invertible? If so, determine the inverse matrix .
Write two square matrices of the same order, calculate and the determinant of the product. What is the relationship between the determinants of and , and the determinant of the product matrix ? Try a few different matrices, then formulate your conjecture.
