Calculator in Control Centre on iPad

Unlike iOS for iPhone, iOS/iPadOS for iPad has never included a calculator. 

One of the very best calculators in the App Store - that happens also to be both completely free and without any advertisements whatsoever - is Sci:Pro Calculator:

Hi there K_Dubs,

iPad doesn't have a built-in calculator. There are lots of third-party apps available in the App Store for this if you need one. For more information about customizing Control Center on your iPad, have a look at this link: Use and customize Control Center on iPad

Take care.
