Doing calculations? Finding a calculator more difficult to use due to reduced vision? Use Siri instead! Siri is a virtual assistant that can perform a variety of tasks controlled by your voice. One of those things is maths calculations. It can convert units of measures, currency and a whole lot more. Currently you will need an Apple smartphone to use it (though from September or so onwards you can also use it from an Apple computer or laptop).
Press and hold your home button, and ask about the calculation you are after,
“How much is 34% of 123?”
Ask for conversions for different measuring units, do divisions, start subtractions…
Quick and easy!
Or – of you have it enabled, you can just start with “Hey Siri, what is (and ask your calculation)”.
