In Mathematics, if two or more numbers are written side by side, i.e., from left to right, they form a row while a column runs in a vertical direction, from up to down. Also, remember that columns and rows may be used interchangeably sometimes, depending on the perspective.
The concept of rows and columns is used in a topic called ‘matrices’ which you will study in higher classes in Mathematics. This matrix has 2 rows and 3 columns.
