This note has been created for everyone who needs help in $\LaTeX{}$ to ask their doubts so that we can become better at $\LaTeX{}$ as a Brilliant Community!

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.

Does anyone know how to align equations?

So for example:

$x^2 + 2x + 1= 9$

$(x+1)^2 = 9$

$x+1 = \pm 3$

The equal signs are not vertically aligned, is there a way to vertically align them?

@Elijah L - Try using \ [ \ ] instead of \ ( \ )

- 3 weeks ago

$x^2 + 2x + 1 = 9$

$(x+1)^2 = 9$

$x+1=\pm 3$

(me trying to use \ [ \ ])

The equations are still not vertically aligned. They're centered, but not vertically aligned.

\begin{align} 2x - 5y &= 8 \ 3x + 9y &= -12 \end{align}

\begin{aligned} 2x - 5y &= 8 \\ 3x + 9y &= -12 \\ ha + m &= za \end{aligned}

@Yajat Shamji hasn't seen my Latex-y solutions yet, or else the Latex Warden's mind would have been blown by now, in the BRILLIathon problems
