Use DuckDuckGo as a Calculator
Just like Google, DuckDuckGo can be used to make even the hardest of calculations thanks to its calculator feature.
All you need to do is type the word calculator into the search bar, and DuckDuckGo will pull out its own calculator at the top of the results.
To make it even easier to use, you can enter your calculation in the search bar, and you’ll get an answer immediately. For instance, you can enter calculator 6 times 16 or just 6 times 16, and DuckDuckGo will show you the result immediately.
