The numbers in swedish
The numbers in swedish and in english are very similar. If, for example, you want to say 75 you just take the word for 70, "sjuttio", and the word for 5, "fem", and put them together to make "sjuttiofem". This works in exactly the same way as it does in english.
One of the differences is that there are two words for the number one, "en" and "ett", which are used together with words of the two different genders. For example you would say "en stol" for "one chair" but "ett bord" for "one table".
Another small difference is that when using the numbers between 100 and 199 you don't always have to use the "one" part in the numbers. For example: to say "105 crowns" you can use one of the two alternatives "etthundrafem kronor" and "hundrafem kronor".
This is also possible with the number 1000, but no other number above that. "Tusen kronor" is possible, but you would have to say "ettusenen" or "ettusenett" for 1001.
