Roman Numerals

When do letters act like numbers? When they’re Roman numerals! In this BrainPOP movie, when Tim and Moby accidentally end up in Ancient Rome, Tim calls on his knowledge of Roman numerals to get them back home. Discover the symbols for 1, 10, 50, 100, 500, and 1,000 and find out how those six letters can combine to make any number you can count to! You’ll also learn how to read Roman numerals as Tim introduces you to the rules of subtractive notation, as well as which numbers you can and can’t subtract from each other. Arabic numbers might be easier to recognize, but Roman numerals are like a whole new language of math!
