# Math equations and science formulas

You can use TeX or LaTeX to add formulas or equations in an activity, both in the title and the answer choices.

Enter your question or answer choice and when you want to insert an equation type, "$$ your equation $$", followed by the rest of your question

**Example:** If $$f(x)=x^3+4x$$, what's the area under the curve for the interval [1,3]?

We'll translate it to mathspeak right then and there with a preview.

The LaTeX will be displayed on the activity chart AND the displayed response page for students to respond via the web...

Or on a students' phone.

If you need some help getting LaTeX syntax down you can try some of these free resources:

If you decide to add equations to your activity after you have created it, you can edit your poll by doing the following:

- Click the title of your poll question to open it.
- Select Edit on the bottom right of the screen.
- Type in your equation with $$ to indicate when it should use LaTeX as described above.

Remember to start your question or answer option with “$$:” so we know to convert it properly.
