Sal defines what it means to add or subtract matrices. He shows a few examples and discusses some important properties of matrix addition and subtraction.

Learn what matrices are and about their various uses: solving systems of equations, transforming shapes and vectors, and representing real-world situations. Learn how to add, subtract, and …

What you will learn in this lesson As long as the dimensions of two matrices are the same, we can add and subtract them much like we add and subtract numbers. Let's take a closer look!

Learn about the properties of matrix addition (like the commutative property) and how they relate to real number addition.

Now try the following matrix addition problems. Notice that each problem involves the sum of a matrix and a zero matrix.

A matrix is a rectangular arrangement of numbers into rows and columns. Each number in a matrix is referred to as a matrix element or entry. If this is new to you, you might want to check …
