Use Of The A And An Questions Medium
No, you cannot use "a" or "an" before numbers. "A" and "an" are indefinite articles used before singular countable nouns to indicate that the noun is not specific or known to the listener. Since numbers are not nouns, they do not require articles before them. However, if the number is followed by a noun, then the appropriate article should be used before the noun. For example, "I have an apple" or "She has a dog."
