Addition and Subtraction Table

To add two numbers (8 + 6), find one of the numbers at the beginning of a row (8). Find your second number at the top of a column (6). Find your answer where the row and column meet (8 + 6 = 14).

To subtract two numbers (14 – 6), locate the larger number in the table (14). Then subtract the number at the top of the column (6). Your answer will be in the row to the far left (8).
