You can use the abs(x) function.

#### Explanation:

To write absolute value bars, use abs function with the hashtags.

When you write ＃abs(x)＃ in the Answer section(＃ must be written in half-width character), you actually see $\left\mid x \right\mid$ in the screen.

... write something like

• without hashtags

|x|

• with hashtags

$| x |$

to get the same result. So just use the vertical bar symbol located on your keyboard to get the absolute value bars in between hashtags.
