Цеmeans It is, here is, and this is.
But "Here is number thirty" was incorrect...
The hints give all translations of the word that are used in the course. Often they are not completely interchangeable. The best translation in the given context is the first one. For this sentence it is "it is."
"Here is" would be "ось (це)."
"Це номер" is correct but everytime I say a number it's incorrect it hears everythimg right except the numbers and I'm pissedddddddd
