This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .

Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.

Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Note: you must add a full line of space before and after lists for them to show up correctly

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 :)

How can I do that using Latex?

Thank you so much.

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.

May I also ask how to do the division operation?
