Home > Math Worksheets > Matrix > Addition of Matrices

Matrix addition is commutative meaning the values can be swapped in the sum problem. This is because ordinary addition is done between matching elements of the two matrices. Regardless of how large the matrices are you match the corresponding positions of the values and find the sum between them to add the two matrices. Operations on matrices are one of the easiest concepts you'll learn in mathematics. However, the rule of mathematics is that there is no room for mistakes in easier calculations. To be able to add matrices both matrices must have the same dimensions (such as 2x2, 3x3, 4x4, etc.) When you are processing this operation you have to add each element one by one. However, you must keep in mind that the order of both matrix operands should be the same.

Your students will use the following activity sheets to learn how to add two 2x2 matrices together in order to create a new, consolidated matrix. Only simple sum will be required at the end.

Addition of Matrices Lesson

If A and B are two matrices each of order m X n, then their sum A + B is a matrix of order m X n and is obtained by adding the corresponding elements of A and B.

Add the first element of the first table with the first element of the second table. Accordingly, add the second element of the first table with the second element of the second table. Perform addition of all the corresponding elements.
