Question: For example,
User adds this "iamsmelly.com".
And if I add an href to this, the link would be
www.mywebsite.com/iamsmelly.com
Is there a way to make it absolute if its not prepended by an http:// ?
Or should I revert to jQuery for this?
Answer: | Probably a good place to handle this is in a `before_save` on your model. I'm not aware of a predefined helper (though `auto_link` comes somewhat close) but a relatively simple regexp should do the job:

class User < ActiveRecord::Base
before_save :check_links

Question: I understand that division by zero isn't allowed, but we merely just multiplied $f(x) = 1$ by $\frac{x-1}{x-1}$ to get $f(x) = \frac{x-1}{x-1}$ and $a\cdot 1 = 1\cdot a = a$ so they're the **same function** but with **different domain** how is this possible?

**Answer**: Maybe simply said it is a map (receipe), $f(x)$, that projects some elements, $x$, contained in a specifically defined set, Domain $D$, into another set, Range $R$.

Question: I was playing some math games intended for children, in Japanese, and the subject was 引き算.

The と is not conditional, and you can tell that from the word followed by the と.
**The conditional と should follow 活用語の終止形/the terminal form of a conjugatable word**, such as verb, i/na-adjective, auxiliary, eg 「話す」「寒い」「静かだ」「〇〇だ... | I think it is an odd way to ask, but the structure is:
* 14 は 10 と いくつ
* 14 = 10 + ?

Question: Is it coherent to suggest that it is possible to iterate, one-by-one, through every single item in an infinite set?
