Let n be natural? What am I missing imma dropout ffs
Yes, this reads as either "let n be an element of the natural numbers" or more simply "let n be natural"
Let n be an image of Arnold Schwarzenegger in the wilderness surrounded by animals with social media icons overlayed because someone was too lazy to spend 10 seconds finding a clean copy of the image.
I think it's let n contain the set of all natural numbers?
No, that symbol means "element of"
∈
Denotes set membership, and is read "is in", "belongs to", or "is a member of". That is, x ∈ S means that x is an element of the set S.
