I'm being told I have a typo in my answer because there is a space before the apostrophe, but that's not my doing: it's Duolingo. (Mentioning this just so you can sort it out for a future update.)
Yeah i have the same problem.
Because of my digital watch I would literally say, "I'm going to be there at or around ten, twenty." Is it common for people to just read off their digital time like that?
Can you say, Deg, tri deg chwech for 10:36? Is that very uncommon?
Why isn't "20 minutes after 10" also acceptable?
how do you say: I go to the cafe at twenty minutes past ten.
After a quick google search, it seems that it is said in the same way.
