A 20x20 Multiplication Chart is a table that contains the numbers 1 to 20 indicated in its topmost row and leftmost column. The table cells contain the products of these numbers. A Multiplication Chart is used to teach multiplication to elementary school children.
To find the product of numbers on the multiplication table, you need to find the first number in the left column and the second number in the top row. Draw a horizontal line from the first number and a vertical line from the second one. The cell where the lines meet is the product of these numbers. You can create a multiplication table on a computer or create a paper version.
