Need to use a scientific calculator on the iPhone? Instead of downloading a new app, just do the following ot instantly transform your iPhone into a complete scientific calculator:

Launch the existing Calculator app on the iPhone either from the Home Screen or by choosing it from Control Center Now physically rotate the iPhone so that the screen orientation is horizontal rather than vertical – this turns the calculator into the scientific mode

Simply rotating Calculator app instantly transforms the normal calculator app into a complete scientific calculator, no visit to the App Store is required, and no additional downloads are needed. Your iphone already has this scientific calculator built right in, supported by all versions of iOS too.

You can switch back to normal calculator just by rotating it back into vertical orientation.

This works on all iPhone models, and it will work on the iPod touch as well, and has been around in iOS for quite some time now but apparently we haven’t posted the tip before. Thanks for sending this neat little trick in Jared!

Oh, and for simpler calculation needs, recall that you can use Siri to perform some basic math too, whether adding things up, getting a percentage or return on a number, and many other math tasks.
