How to type in fractions

[lingping7]

Normally it would be written as 1/2. 3/5. 83 3/6.
But I've seen some people typing it like the way we write it like numerator on one line, denominator on the other.
I was wondering how to do that because when it's a big problem, it'll look confusing.

And then to enclose the whole fraction in brackets and root it or square it?

The kind of presentation you are asking about uses a language called LaTex, which is quite fussy. I do not recommend students learn it because it is more important for them to focus on math itself rather than neat presentation. It is up to us to parse your questions so long as you remember proper order of operations. If you know and follow PEMDAS, it is our job to figure it out.

I've only posted about 20 times, and I've learnt \frac, \displaystyle\lim, \re, \infty, \to, \cdot, \left(, \right), \sqrt and once I did a split function

You could consider MathType. No need to learn LaTex. See related old post here.
