Another useful feature of a phone is a that most of the phones include a calculator application. Now I agree that for most phones the function it includes is basic and cannot replace a standalone calculator, but lets face it, a mobile phone is not meant to be a calculator, that is just one of the added features.
Now you may say, What is the point of a having a calculator in a Mobile phone? Well for one it adds more functionality to your phone and can be used at almost anytime. Now because most people always carry Mobiles with them its useful to do away with other devices. So if you are shopping and you have limited funds and don’t want to embarrass yourself at the check out you could quickly snap out your phone and work out your expected bill. Or if you are at a restaurant and want to split the bill among your friends you can use your phone to quickly tell you how much each one has to say.
The possibilities are endless.
So the next time you need to do some math and you feel lazy to do it in your head don’t feel shy to get your handy Mobile out and keep your brain stress free.
