How to use Generate Tables
- 1. Pick the operation. Choose Multiplication, Addition, Division, or Modular arithmetic. This decides what fills each cell of the grid: products, sums, quotients, or remainders.
- 2. Choose the table size. Set Size to control how many rows and columns the table spans, for example 12 for a classic times table or 5 for a compact one to fit in a slide.
- 3. Set the modulus for modular tables. If you chose Modular arithmetic, set Modulus to the number everything wraps around, useful for visualizing cyclic groups or clock arithmetic.
- 4. Copy the finished table. The table renders as aligned plain text with row and column headers. Copy it into a worksheet, a code comment, or a chat message.
When to use Generate Tables
Generate Tables builds addition, multiplication, division, and modular arithmetic grids of any size. It replaces the manual work of drawing a times table or a Cayley table cell by cell for teaching, reference, or quick verification.
- Making a classroom worksheet. A teacher needs a fresh 12x12 multiplication table each week so students cannot memorize the answer key from last time, and wants it as plain text to drop into a printable handout.
- Studying modular arithmetic. A student learning group theory wants to see the addition table modulo 7 laid out fully, to spot the cyclic structure before tackling abstract Cayley tables in a textbook.
- Sanity-checking a division algorithm. A developer debugging integer division in a new language wants a reference division table for small numbers to compare against unexpected output from their own code.
- Building a reference chart for a spreadsheet. Someone setting up a pricing sheet with tiered multipliers wants a quick multiplication grid to paste in as a lookup reference before writing the real formulas.
Examples
3 × 3 multiplication table
Output
× 1 2 3 1 1 2 3 2 2 4 6 3 3 6 9
About the Generate Tables tool
Generate Tables runs as plain JavaScript in your browser tab, with no server behind it. Addition, multiplication, division, modular arithmetic. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Math Tools section, 234 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 3 settings, including Operation, Size and Modulus, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Does Generate Tables cost anything?

How do I get a different result?
Run the generator again. Each run is computed fresh on your device, and any options you change are applied to the next result immediately.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
