Mandarin numbers from 1 to 100 follow a clear building pattern, which makes them easier to learn than many students expect. Once you know the numbers 1 to 10, you can combine them to make almost every number up to 99. This skill matters because numbers appear in prices, dates, phone numbers, classroom directions, and travel situations.
Learning the tones with each number is just as important as memorizing the spelling.
Key Facts
- 1 to 10: 一 yī, 二 èr, 三 sān, 四 sì, 五 wǔ, 六 liù, 七 qī, 八 bā, 九 jiǔ, 十 shí.
- 11 to 19 use 十 + ones: 11 = 十一 shí yī, 12 = 十二 shí èr, 19 = 十九 shí jiǔ.
- 20 to 90 use tens digit + 十: 20 = 二十 èr shí, 30 = 三十 sān shí, 90 = 九十 jiǔ shí.
- 21 to 99 use tens digit + 十 + ones digit: 46 = 四十六 sì shí liù, 78 = 七十八 qī shí bā.
- 100 = 一百 yì bǎi, often heard with a tone change from yī to yì before bǎi.
- Tones change meaning, so 四 sì is 4, but pronouncing the wrong tone may make the word unclear.
Vocabulary
- Hànzì
- Hànzì are Chinese written characters, such as 一, 二, 三, and 十.
- Pinyin
- Pinyin is the Roman letter system used to show how Mandarin words are pronounced.
- Tone
- A tone is the pitch pattern used when saying a Mandarin syllable, and it can change the meaning of a word.
- Shí
- Shí means ten and is the key building block for Mandarin numbers from 10 to 99.
- Yì bǎi
- Yì bǎi means one hundred and is written as 一百.
Common Mistakes to Avoid
- Saying 一十 for 10 instead of 十 is wrong in normal counting because Mandarin usually says just shí for 10.
- Forgetting 十 in numbers like 23 is wrong because 二三 means two and three separately, while 二十三 èr shí sān means twenty-three.
- Using English word order for 47 is wrong because Mandarin says four-ten-seven, 四十七 sì shí qī, not seven plus forty.
- Ignoring tone marks is wrong because pinyin without tones does not fully show Mandarin pronunciation, and numbers like sì, qī, and shí need accurate tones.
