I feel really bad if I think about all those non Polish speakers dealing with it. ;(

Třista třicet tři střibrnch střkaček stříkalo přes třista třicet tři střibrnch střech... Polish isn't the only language with horrible words :D

What about:
גנן גידל דגן בגן, דגן גדול גדל בגן.
Deal with it

W Mszczonowieścicach, gmina Grzmiszczosławice, powiat Trzcinogrzechotnikowo ;)

Man who invented "szcz" was a genius.

Yes, it is very hard for me to memorize everything, especially that Duo does not teach from 1-10, 11-20, etc. It jumps off from 1, then 4-5, then 17-20 that is why it is soooo confusing. And the spelling, too. :(

If you want to learn the Polish numbers from 1 to 100, I reccomend you Memrise to do it, because Duolingo it's better for learn words, but Memrise it's better for learn numbers.

"17 18 19 20" is accepted :D

Polskie numery: nie boję się was! Przezwyciężę. :)
