Romblomanon language facts for kids
Have you ever wondered how people counted before we had the numbers 0, 1, 2, 3, and so on? For thousands of years, different cultures around the world created their own unique ways to count and write down numbers. These systems, called numeral systems, helped them keep track of everything from goods and trade to time and astronomy. Let's explore some of these fascinating ancient and modern counting methods!

Counting Through Time: Different Numeral Systems
For a very long time, people have needed ways to count things. Imagine trying to trade goods or build a huge pyramid without a way to keep track of numbers! Different civilizations came up with clever solutions, and many of these systems are still around today or have influenced the numbers we use.
Ancient Counting: From Clay to Hieroglyphs
Long, long ago, people used all sorts of methods to count. Some of the earliest systems were quite different from what we use now.
Babylonian Numerals: Counting in Sixties
Around 3,100 BCE, in ancient Mesopotamia (where Iraq is today), the Babylonians used a unique system based on the number 60. This is called a base-60 system. It's why we have 60 seconds in a minute and 60 minutes in an hour! Their numbers looked like wedges pressed into clay tablets.
Egyptian Numerals: Pictures for Numbers
The ancient Egyptians, around 3,000 BCE, had a system based on 10, just like ours. But instead of simple digits, they used hieroglyphs (picture symbols) for numbers. For example, a single stroke meant 1, a heel bone meant 10, and a coiled rope meant 100. They would repeat these symbols to make larger numbers.

Aegean Numerals: Minoan and Mycenaean Counting
Around 1,500 BCE, civilizations in the Aegean Sea region, like the Minoans and Mycenaeans, also used a base-10 system. Their numerals were found on clay tablets and were used for keeping records of goods and supplies. They had distinct symbols for 1, 10, 100, 1,000, and even 10,000.
Famous Systems: Roman and Asian Numerals
Some numeral systems became very famous and were used for a long time, even influencing how we see numbers today.
Roman Numerals: Letters as Numbers
You've probably seen Roman numerals! They were used by the ancient Romans around 1,000 BCE and are still used sometimes today, like on clock faces or for numbering chapters in books. This system uses letters from the Latin alphabet to represent numbers:
- I = 1
- V = 5
- X = 10
- L = 50
- C = 100
- D = 500
- M = 1,000
To make other numbers, they combine these letters, often placing smaller values after larger ones (like VI for 6) or before them to subtract (like IV for 4).
Many East Asian languages, including Chinese, Japanese, and Korean, share similar numeral systems that are based on 10. These systems have been around since at least 1,600 BCE. While the characters might look different depending on whether they are traditional or simplified, the basic idea of using specific characters for 0-9, 10, 100, 1,000, and so on, is the same.
- 零 (líng) - 0
- 一 (yī) - 1
- 二 (èr) - 2
- 三 (sān) - 3
- 四 (sì) - 4
- 五 (wǔ) - 5
- 六 (liù) - 6
- 七 (qī) - 7
- 八 (bā) - 8
- 九 (jiǔ) - 9
- 十 (shí) - 10
The Numbers We Use Today: Hindu-Arabic System
The numbers we use every day – 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 – are part of the Hindu-Arabic numeral system. This system was developed in India between 750 and 690 BCE and later spread to the Arab world and then to Europe. It's a base-10 system, meaning it uses ten different digits, and it's also a positional system. This means the place of a digit matters (e.g., the '2' in 20 is different from the '2' in 2). This clever idea made calculations much easier!
Eastern and Western Arabic Numerals
The Hindu-Arabic system evolved into different forms. The "Western Arabic numerals" (0 1 2 3 4 5 6 7 8 9) are what most of the world uses. But there are also "Eastern Arabic numerals" (٠ ١ ٢ ٣ ٤ ٥ ٦ ٧ ٨ ٩) used in many parts of the Middle East and South Asia. Both come from the same origin.
Unique Counting Systems: Maya and Kaktovik
Not all numeral systems are based on 10. Some cultures developed very different ways of counting.
Maya Numerals: Dots, Bars, and Shells
The ancient Maya civilization in Central America, before the 15th century, used a fascinating base-20 system. Their numbers were made up of dots (for 1), bars (for 5), and a shell-like symbol (for 0). This system was very advanced for its time, especially because it included the concept of zero.
Kaktovik Inupiaq Numerals: Counting on Fingers and Toes
A more recent and very clever system comes from the Inupiaq people of Kaktovik, Alaska, developed in 1994. Their numeral system is also base-20, designed to be easy to use with their traditional counting methods, which often involved using fingers and toes. The symbols are quite unique and visually represent groups of 5, 10, and 20.
