Single-entry matrix

A single-entry matrix is like a table that is used to organize information. It usually has two rows and two columns. The first column is called the 'input' column and it contains the info that you want to organize. The second column is called the 'output' column and it contains what you want the info in the input column to do or be. For example, if you were organizing the names of different types of food, the input column would have a different type of food written in each row, and the output column would say what kind of food it is (fruits, vegetables, meats, etc).
