Translation:Siedem to moja liczba.
"Siedem to mój numer" should be accepted too
cyfra and liczba is practically the same, it should be accepted too
Well... they're not the same. But 7 is a digit, so ok, added.
what's wrong with numer? numer means number?
"Siedem to mój numer" is accepted, it should have worked.
siedem to jest moja liczba?
Geez. Yeah, technically yes, but that's rare. Added.
