I don't get the point of it? So, I'm not sure so please correct me if I'm wrong (This is my question)
Say I have, 3 crates of apples but I want to show how many per crate would I do?
Like A (Apples) and a 3 below it slightly to show that I have 3 of those? and a five as the exponent to show that there are 3 crates with 5 apples in each?
