Roman Numerals - Learn

Finally master Roman numerals, from I (1) to MMMCMXCIX (3999), with a clear, step-by-step method designed for everyone.
Whether you want to decipher the date carved on a monument, understand a chapter number, read the time on a classic clock or simply out of curiosity, Roman Numerals - Learn guides you step by step, at your own pace.

HOW IT WORKS
The app is organised into 6 levels, from the simplest numbers (1 to 8) to the largest (900 to 3999). Each level introduces one or more new symbols and the rules that go with them: addition, subtraction, allowed repetitions. The explanations are deliberately simple and illustrated with concrete examples, with no unnecessary jargon.
Once the lesson is done, four types of exercises let you check and reinforce what you have learned:
• Match an Arabic number to the corresponding Roman numeral
• Match a Roman numeral to the corresponding Arabic number
• Write the Roman numeral from an Arabic number
• Write the Arabic number from a Roman numeral

TIMED CHALLENGE
Once you have the basics, test yourself in the Timed Challenge: chain together correct answers, with all sections mixed, at 30 seconds per question. Every run keeps your personal best up to date, and you can share it with friends and family.

REVISION AND CONVERTER
Need a quick reminder? The Revision screen sums up the basic symbols and the essential rules at a glance. The built-in converter instantly turns a Roman numeral into an Arabic number, and vice versa.
