Download PDFTo read the chart, find one factor in the column on the left and the other in the row across the top. The cell where that row and column meet is the product. For 23 × 17, go to row 23 and move across to column 17: 391.
A chart to 25 goes past the 12 × 12 facts students memorize. It is a reference for two-digit multiplication, for checking long multiplication and division, and for finding factors: every place a number appears in the grid is a pair of factors for it. A heavier line every five rows and columns helps the eye stay on the right row.
Squares up to 25 × 25 = 625 are worth knowing by heart for middle school work on square roots and the Pythagorean theorem. They run down the diagonal and are shaded yellow on the color chart.
For the standard sizes (10 × 10, 12 × 12, 15 × 15, 20 × 20) and single times tables, see the main multiplication chart page, or the larger 1-30 chart.
