ROMAN NUMERALS: I V X L C M • If you have ever tried to write big numbers in Roman numerals, you have some idea of how much easier it is to use Arabic numbers with zeroes. • Roman numerals were designed for accounting (sacks of grain, etc.) One thing was I; two things were II; three things were III.
I V X L C M • Roman numerals looked like human hands. It was too difficult to see more than four individual strokes, so after four a line was drawn across the IIII to make V. And after V plus IIII a line was drawn the other way against the VIIII to make X. For higher numbers new letters were needed so we get L for fifty, C for 100, M for 1000 and so on.
ARABIC NUMBERS:٠١٢٣٤٥٦٧٨٩ • We use a Roman alphabet for our writing system, but we don’t use the Roman numeral system for addition, subtraction, multiplication or division because it’s too cumbersome. • Whenever you count or do math, you are paying homage to Arabic mathematicians. • As English speakers, we took our numbering system from the Arabs. The reason we did this is that the Arabs figured out how to use a zero as a place marker. • Arabic zero ٠looks like English 0. They are both circles, however the Arabic circle has a radius of zero.
٠١٢٣٤٥٦٧٨٩ • Arabic ١, like English 1 has one stroke. • Arabic٢ like English 2 has two strokes. The English 2 is the same as the Arabic except that it is sideways. • Arabic ٣ has three strokes, and is like an English 3 only sideways. • Arabic ٩ is like English 9. • See if you can use these numbers to connect the dots to finish drawing the Blue Mosque, which was one of the prettiest buildings in Kabul.
