Multiplication Tables

Generate custom multiplication tables for any range. Hover over cells to highlight rows and columns, and identify perfect squares.

How It Works

A multiplication table arranges products of two numbers in a grid. Each cell shows the result of multiplying its row header by its column header. For example, the cell at row 3 and column 4 contains 3 × 4 = 12.

Features:

• Custom range — Generate tables from 0–100 in any range
• Highlight — Enter a number to highlight its entire row and column
• Perfect squares — Cells where row = column (e.g. 7 × 7 = 49) are marked with a border
• Hover — Move your mouse over any cell to see cross-highlights
• Export — Download the table as a CSV file
• Print — Print the table with a clean layout

Multiplication Patterns

Multiplication tables reveal several useful patterns:

• Commutative property — The table is symmetric along the diagonal (3 × 5 = 5 × 3)
• Diagonal — The main diagonal contains perfect squares (1, 4, 9, 16, 25, ...)
• Multiples of 5 — Always end in 0 or 5
• Multiples of 9 — Digit sums always equal 9 (e.g. 27 → 2+7 = 9)
• Even numbers — Any number multiplied by an even number gives an even result
