Google has quietly added a nifty calculator to its search engine. The new calculator appears after you type a search query involving an equation and allows you to perform both simple and complex calculations without navigating away from the main site. A search for “calculator” will also toggle the web-based calculator.

A compact version of the calculator is available via the mobile browser on both Android and iOS devices (hint: rotate your mobile device to the side bring up the full calculator).

The calculator will be a useful addition for people who want to complete multiple equations without having to navigate away from the first page of Google’s search results.
