If n represent the number of apples you buy can n= 1 be a number of apples you buy

Question

It don't matter

Answer 1

Although you say It Don't Matter, your answer is yes, n = 1 can be a number of apples you buy. But only if you buy just one apple.

 

Since we're in the real world here, I'd restrict n to the realm of the natural numbers (positive integers).
