Yes , I can. In Brainly it's called as latex. It's an attractive way of writing answers.

tex and \tex

= {\huge{\boxed{tt{\color{steelblue}{Answer}}}

= {\small\color{pink}{Answer}

You can change the color; Where I have written "pink" or "steelblue" instead of that you can write orange , yellow , blue , navy etc.

And you can also change the Answer and instead of that h can write anything you want to.

But remember , always start with [tex] and end with [\tex]

There would be a (+) sign in the left corner , click that.

Click that too. Then write these things in the box given , and there would be an insert button , click that.

So you would be able to write it.
