Math Reference Tables

A math reference table is an essential tool for students, engineers, programmers, and professionals alike. These tables collect pre-calculated values so you can find results instantly without performing repetitive calculations. They span a wide range of disciplines: arithmetic, number theory, computer science, electronics, geometry, and mathematical symbolism.

This collection includes over 20 tables organised by category. From multiplication tables to Roman numerals, from the ASCII table to HTML colours, from resistor colour codes to AWG wire gauges — every table is directly accessible and optimised for quick reference.

How to Use Math Reference Tables

Reference tables speed up your work by eliminating repetitive calculations. A programmer who knows the ASCII table can instantly identify the code for any character; an electrician who uses the resistor colour code table can read component values without measuring instruments. Having the right table at hand turns a multi-step calculation into a single lookup.

There is an important difference between a static reference table and a calculator: a table reveals patterns and relationships that a calculator never shows. Looking at the multiplication table exposes symmetries (the commutative property), perfect squares on the diagonal, and recurring patterns in the multiples of 9. These insights build mathematical intuition over time.

How to search efficiently: to find a specific value (such as the Roman numeral for 2026), use the link to the individual entry in the Roman numerals table. To explore patterns (such as all prime numbers up to 100), use the full table view. Each table on this site is designed for both targeted lookups and broad exploration.

Frequently Asked Questions

What is the multiplication table up to?: Our multiplication table covers 1×1 through 12×12 (the standard school range), with additional pages for 1–20 and 1–100. Individual times tables for each number from 1 to 12 are also available.
How many ASCII codes are there?: The standard ASCII table contains 128 characters (codes 0–127), including control characters, digits, uppercase and lowercase letters, and punctuation. Extended ASCII adds another 128 codes (128–255) for special characters and symbols.
What is the largest prime number in the table?: Our prime numbers table lists all primes up to 1000. The largest prime below 1000 is 997. There are 168 prime numbers between 1 and 1000.
How do I read a resistor color code?: A standard 4-band resistor has: band 1 (first digit), band 2 (second digit), band 3 (multiplier), band 4 (tolerance). For example, Brown-Black-Red-Gold = 1-0 × 100 = 1000 Ω ±5%. Use our resistor color code table for a complete reference.
