Latex for Vertical Math Operations

How can I do math operations in Latex that goes down vertically? Instead of $1+2=3$ , how can I do the one where it goes down by solving?

How can I do that using Latex?

Thank you so much.

@Kaizen Cyrus – Sure, you're welcome!

Is there a way to somehow make the horizontal line to be directly at the top of the sum? There's so much space between them.

@Kaizen Cyrus – Something that looks like now? Then remove the the the extra line of \

@Mahdi Raza – Got it. Very appreciated. Thanks for responding.

@Kaizen Cyrus – You're welcome. Ask if you have any more queries! Good luck!

May I also ask how to do the division operation?

Kaizen Cyrus - 1 year ago

Sure, you can use \frac{1}{2} with {1} brackets for numerator and {2} denominator respectively. When wrapped in latex, this will result in something like this $\frac{1}{2}$

Is it possible as the same manner as your first comment? As in the division operation is going down vertically like it is being solved in an elementary school.

You can use online $\mathbf{LaTeX}$ editors and the Chrome Easy Math Editor as well as the Formatting Guide to assist you in mathematical operations. Hope this helps :)
