pay attention to
The same number represents different values because of different digits. For example, if Arabic numerals are used to represent numbers, the same' 6' in the tenth place is six tens, in the hundredth place is six hundred, in the hundredth place is six hundred, and in the hundredth place is six hundred million.
The counting unit on "unit" is "one", the counting unit on "ten" is "ten" and the counting unit on "hundred" is "hundred", so look at the numbers first and then look at the counting unit. For example, 9063200 is pronounced as 9063200, and 10,000 and 100 are counting units.
