Typing the double backslash "\\", typing the double dollar-sign " $$ " and clicking the arrow-X in the menu above all put you into math mode. Just remember that whichever you choose to open your math with should be the same thing that you use to close your math with.

Clicking on the "%" icon above the post editor will automatically give you the math mode wrapper of "'''"s.

The wrapper comes with a very fancy sophisticated code example, highlighted in \(\textcolor{blue}{\text{ blue }}.\) Go ahead and delete this, because you are about to put in your own fancy sophisticated code.

Type your code directly inside this wrapper. Please keep in mind that to make a new line, typing "enter" won't automatically do it for you. You will have to type **two backslashes at the end of each line**.

```
3 \times 4 \\
x \times y \times y \\
0.5 \times 1.\overline{111}
```

I personally like to use the backslashes because I find it easier to keep my hands on the keyboard without having to go for the mouse. With this method, you must type in the "wrapper" yourself. This is two backslashes, followed by an open parentheses / close parentheses. If you use curvy brackets, you get inline Latex that can sit inside your sentence.

```
There are random math \\(x^2\\) symbols \\(2^2\\) appearing \\(\frac{1}{2}\\) in this \\(x^y\\) sentence.
```

If you use square brackets, you get Latex on its own line.

```
There are random math \\[x^2\\] symbols \\[2^2\\] appearing \\[frac{1}{2}\\] in this \\[x^y\\] sentence.
```

Typing two dollar signs will also open and close your Latex code. However, it gives e x t r a h u g e spacing, and will set the math on its own line.

```
3 \times 4
x \times 4 \times y
0.5 \times 1.\overline{1111}
```

```
3 \times 4
x \times 4 \times y
0.5 \times 1.\overline{1111}
```

With wrapper:

```
3 + 2 = 5
3 + 2 \neq 4
3 + 2 > 5
3 + 2 \geq 4
2 + 2 \leq 5
2 + 2 = 4
3 + 2 > 4
```

When typing fractions, it helps to first type the empty braces, like this:

```
\frac{}{}
```

before you enter the values into the braces.

```
\frac{123456}{7890}
```

This way, you're less likely to make a typo!

```
\frac{1}{2}
\frac{1}{2 + x}
\frac{\frac{1}{2}}{x}
\frac{1}{2} \times \frac{x}{3}
\frac{1}{2} = x
```

With wrapper:

Superscripts, subscripts and degree notation. Remember that if the superscript or subscript is more than one digit, you need braces { } around it.

```
x^2
x^{30}
360^{\circ}
x_1, x_2, x_3, ldots
x_{20}
```

With wrapper:

```
\angle ABC
\bigtriangleup ABC
\overline{AB} = 3
x \approx 3
\angle A = 30^{\circ}
\frac{ \overline{AB}}{\overline{BC}} = 2
```

With wrapper:

Aligned equation blocks:

```
\begin{aligned}
3x + 2 &= 7 \\
6x + 4 &= 14 \\
x &= \frac{5}{3}
\end{aligned}
```

]]>Thanks for asking! You can type the Sigma \( \sum \) by itself like this:

```
\\( \sum \\)
```

or as the sum of a sequence of terms, like this:

```
\\( \sum_{n=1}^{n=10} n^2 \\)
```

\( \sum_{n=1}^{n=10} n^2 \)

```
\\( \sum_{n=1}^{\infty} n^2 \\)
```

\( \sum_{n=1}^{\infty} n^2 \)

I hope this helps!
