In English you might simply say "That is my number." Is it the same in german? i.e could you say "Das ist meine Nummer"?
You can say it but it is not the best way to say it
I want to know this also.
How does it mean this and that?
I thought diese, dieses, dieser meant this and das means that?
Well, "das" can mean all sorts of things, including this, that, these, and those.
Is there any sort of guidance for when we should translate as "this" vs. "that"?
Is also accepts “This is my phone number“
So Telefonnummer is feminine?
yes, for most words if you check the dictionary hints it will show the word's gender at the bottom
Thanks. Apparently, it gives you the gender only when you use duolingo from the computer, but not when using Duo from the smartphone...
Yes. Nummer is feminine and whenever a word is made from two or more other words, the gender of the combined word is always derived from the last word:
That's what she didn't say.
