Approximate Numbers with 多 in Chinese
数词和多表示概数
多 can follow a round number before a classifier, as in 三十多本书, or follow a complete numeral-unit expression, as in 三块多. Both patterns give an approximate amount slightly above the stated number. The placement depends on whether the classifier or unit belongs inside the quantity already reached.

Read the structure
多 can follow a round number before a classifier, as in 三十多本书, or follow a complete numeral-unit expression, as in 三块多. Both patterns give an approximate amount slightly above the stated number. The placement depends on whether the classifier or unit belongs inside the quantity already reached. Keep the model Round Number + 多 + Classifier + Noun; Number + Classifier/Unit + 多 visible while you compare each sentence.
我买了三十多本书。
I bought more than thirty books.
Choose the right context
Put 多 after a round number and before the classifier for an approximate count. Put 多 after a complete numeral-unit phrase when the excess is smaller than that unit. Use the pattern when the real quantity is slightly above the named number.
这个西瓜有五十多斤。
This watermelon weighs over fifty jin.
Respect the boundary
Do not place 多 inside the digits of a numeral. Do not split a classifier from its following noun with 多. Do not use this pattern for a quantity below the named number.
我买了三十本多书。
(I bought thirty classifier more books.)
Repair the pattern
多 separates the classifier from its noun: For a count above a round number, 多 follows the number and precedes the classifier-noun phrase. 多 is inserted inside the numeral: The numeral 三十 must remain intact before approximate 多.
我买了三十多本书。
Use the repaired structure without changing the intended meaning.

08 / QUESTIONS
Approximate Numbers with 多 Questions
Does 三十多 mean about thirty or more than thirty?
It means an unspecified amount slightly above thirty. The context determines the practical upper range.
Why can 多 occur after 块 in 三块多?
块 is the unit already reached, and 多 adds an amount smaller than one more full unit. This differs from 三十多块, where 多 follows the round number.
