My favorite thing I have learned in history are the Arabic and Roman numerals. The Arabic numerals are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. We use them to make multi-digit numbers like 23, 65, 89, 123 and beyond. We use Arabic numerals every day when we are multiplying, dividing, subtracting, and adding. Roman numerals are another way of writing numbers. The Roman numerals are I, V, X, L, and more. The letter “I” means one, “V” means five, “X” means ten, and “L” means 50. Roman numerals are sometimes used to number pages and chapters. Before Arabic numerals the Romans used Roman numerals to write numbers. Why Arabic and Roman numerals are my favorite is because both are used for math.
