So this is probably a super easy question for Math Stack Exchangers. Anyways I can determine the multiples of 3 up to 10 doing this.
multiples of 3 up to 10
0*3 = 0
1*3 = 3
2*3 = 6
3*3 = 9
What would this look like as an equation? Like I said this is in my opinion a very elementary approach and I would like to learn a more advanced way of doing this using proper terminology. Any help is much appreciated. Thanks.
FYI, this probably will need to be re-tagged as I have no idea how to even tag this question, so I am going to just guess.
The nonnegative multiples of $3$ have the form $3n$ for natural $n$. If you want to write the set of all of these multiples of $3$ with notation rather than words, you can write $\{3n\mid n\in\mathbb N\}$. If you want to write the set of these multiples of $3$ that are less than $10$, you can write something like $\{3n\mid n\in\mathbb N,n<10/3\}$.
You said "as an equation", but an equation is something with an equals sign, and there aren't really any natural things to write with an equals sign to describe this collection of numbers.
