百 · 零
Hundreds, then tens, then units; an empty place in the middle is read 零
Structure
数字 + 百 （+ 数字 + 十 + 数字） · 中间空位读 零
What it means
For 100–999, say the hundreds, then the tens, then the units. An empty place in the middle is read 零 (zero).
How it is built
Number + 百 + number + 十 + number: 一百二十 (120). Empty tens place → 零: 一百零八 (108). 100 is 一百.
When to use it
In speech 一百 sounds yìbǎi (the 一 tone change from lesson p-3), but the course writes yī bǎi. Everyday short form: 一百五 = 一百五十 (150).
Watch out
✗ 百 alone ✓ 一百 (100). Don't drop 零: 一百零五 is 105, but 一百五 is 150. Inside a bigger number 10 keeps its 一: ✗ 一百十 ✓ 一百一十 (110).
