## What is a matrix addition?

This tool adds matrices. The matrix sum is calculated by adding the corresponding elements of two matrices. The matrices should have the same number of rows and columns and as the result you get a matrix of the same size as input matrices. When you enter matrices, you can separate them using a pipe, if they're entering them horizontally or a plus, if you're entering them vertically. You can add several matrices using different separators. You can also select the separator between the elements and rows for the initial matrices and their result. If the result isn't very readable, you can beautify it by enabling beautify output matrix option, which will even out matrix elements by adding spaces between the numbers. Mathabulous!
