How do you write on latex like this

##A = (1+2) * (4+7) * (2+9)##
##= 3 * 11 * 11##
##= 363##

##A = (1+2) * (4+7) * (2+9)
= 3 * 11 * 11
= 363##

How do you align at = in Latex?

Thank you

The double backslash gets you a newline, and you can align equations using the "align" environment.
A multiplication sign is \times.
You can also size the parentheses.

$$A=(1+2)(4+7)(2+9) \\=3\times 11\times 11 \\= 363$$

Using the align environment and sizing the parentheses:
\begin{align} A &=\big(1+2\big)\big(4+7\big)\big(2+9\big) \\ &=3\times 11\times 11 \\ &= 363 \end{align}

If you are going to be using LaTeX more (recommended) then you'll need a decent guidebook:

For LaTeX on PC, the standard and probably easiest way to go is Miktex It contains the latex engine, simple editor and previewer.

Oh yeah...

... see the latex project for more.

There's also a short intro on the help page...

LaTeX is a complete document typesetting system, not just for typesetting maths.
Using it in place of the built-in equation editor in a wysiwig editor like word is a bit more involved.

I use commandline with TexLive myself... but then it comes with the os.
