Matrix representation

Matrix representation is a way of arranging numbers in rows and columns so that it is easy to solve and think about problems. It is like a big grid with lots of squares, and each square can hold a number. We can use the rows and columns to organize information and solve problems. For example, if we wanted to add two numbers together, we could add the numbers in the row and in the column, like this:

| | X | Y |
|---|---|---|
| A | 4 | 6 |
| B | 2 | 1 |

The total of X is 6 (4 + 2) and the total of Y is 7 (6 + 1). So the total of the matrix would be 13 (6 + 7). It is like a puzzle, but instead of arranging pictures or shapes, the pieces are just numbers. Matrix representation is a very useful tool for organizing numbers and finding solutions to problems.
