# Calculate Simple Math Quickly in OneNote

Did you know that you can solve a wide range of math problems in OneNote?  Whether you’re taking notes in class and working homework in OneNote or simply need to solve some quick math, here’s how you can use OneNote to help you out.

OneNote is a great tool for taking notes, keeping outlines, and more.  It makes it easy to keep your info organized and connected, and lets you include a wide range of data in your notes.

One slightly hidden OneNote feature is its ability to solve math problems.  Simply enter a simple equation with an equals sign, press Enter or the spacebar on your keyboard, and OneNote will automatically calculate the result.

OneNote can calculate SIN, COS, logarithms, radians, and more.  Here’s a longer equation we solved directly in OneNote; just write out your equation as you’d enter it in a scientific or graphing calculator, and it’ll calculate the results just like you’d expect.

You can solve factorials in seconds, or find the remainder with the mod function.

OneNote also works with the Greek letters used in mathematics, such as π and φ.  To add these to problems, click the Symbol button in the Insert tab, and select the symbol you need.

Here we solved a problem with π:
