This matrix subtraction calculator can help you calculate the subtraction of two matrices while they can have 2x2, 3x3 or 4x4 rows and columns. You can understand better the calculation process by going through the example provided below the tool.

## How does this matrix subtraction calculator work?

This matrix subtraction calculator can assist you when making the subtraction of 2 matrices independent of their type. They can be 2x2, 3x3 or even 4x4 in regard of the number of columns and rows.

In algebra, the **matrix subtraction** between a matrix A and another one called B is allowed only if both matrices have the same number of rows and columns. For instance if A is a 2x3 matrix, then B should have 2 rows and 3 columns as well. The subtraction operation requires that each pair of the two corresponding entries to be subtracted, which in other words means that the entry from row 1, column 1 from B is subtracted from its corresponding entry from A row 1 column 1.

An example is given here:

This matrix subtraction calculator allows both positive and negative numbers, with or without decimals and even values expressed by fractions. For fractions you have to use "/" sign: for example you can input 1/3 or 1/5.
