Numbers up to 20:

Note: Ett is neuter, en is uter; "the digit 1" is "siffran ett" in Swedish. Especially when counting, four is often pronounced as fyr. Nio and tio are commonly pronounced as nie, tie, respectively. Tjugo is usually spelled tjugi, and so on with the following multiples of ten (tretti instead of trettio, förti instead of fyrtio , etc.). Forty is never pronounced the way it is spelled (fyrtio), it becomes förti(o).

Particularity in writting the date:

Note: To make numbers between these, you add a number 1-9 not in parenthesis, e.g. 55 is femtiofem, 73rd is sjuttiotredje, 20,000 is tjugotusen. However, tjugo is in this case commonly pronounced as tju, e.g. tjuåtta for 28. The -tio ending is commonly pronounced as -ti but not in the parenthesis case. Fyrtio is pronounced as förti and sometimes written as förtio. One commonly only say etthundra to distinguish it from e.g. tvåhundra. As you might have guessed, Swedish uses the same system for large numbers as e.g. the UK, not the system used in the US.
