You can post mathematical symbols by clicking on the **x/2**

and on the $\sqrt{x}$ symbol on the bottom of the editing menu above, when you are in edit mode. The editing menu/screen looks like this:

By clicking on the $\sqrt{x}$, you will be writing a new equation in a separate line, for example

[[math]]

nCk=\frac{n!}{k!(n-k)!}

[[/math]].

Notice that the equation will then be numbered. Such equations are written between [[math]] and [[/math]].

By clicking on the **x/2**, you will be writing a new equation in the same line, for example $nPk = \frac{n!}{(n-k)!}$.

Such equations are written between [[$ and $]].

The mathematical symbols in between are written in Latex.

Here are some examples:

- To write fractions type *\frac{}{}*, for example:
- \frac{2}{3} is $\frac{2}{3}$
- \frac{2+x}{x-y} is $\frac{2+x}{x-y}$

- To write powers type ^:
- 3^2 is $3^2$
- {x^y}^z is ${x^y}^z$

- To write a square root, one types
**\sqrt{ }**, for example- \sqrt{64x^2}=8x is $\sqrt{64x^2}=8x$ assuming that $x\ge 0$ (typed x \ge 0 for the inequality).

- To write the sigma sign for sum, one types
**\sum**, and if one wants to specify the limits of this sum, those are introduced with *_* (lower limit) and**^**(upper limit), for example: - \sum\limits_{i=1}^{10}=1+2+3+…+9+10 = 5050 is $\sum\limits_{i=1}^{10}=1+2+3+...+9+10 = 5050$

You should be able to read mathematics signs on your computer. Read the next post and verify if you can read the mathematical symbols in it.
