(Native Marathi, competent Hindi speaker here. Marathi has the same problem) So, it's not like each number has a different name. However, it's almost like that. Basically, the numbers can be broken down into a logical tens and ones place -- e.g. 45 will be five-forty (paintalees -- pai/talees), however the exact way to say "five" will change based on the number, as will the exact way to say "forty". There's not much logic to it -- some tens series are more regular than others -- which means you effectively end up memorizing it, but subconsciously. Imagine numbers in English but there were three ways of saying each digit, and each number 1-100 would pick from the synonyms. It's basically like that. That is to say, it's not too hard to deal with -- you'll mentally be associating the numbers with their words so it's not hard to say it out, and because they're synonyms not hard to understand when spoken.
