Google CalculatorGoogle has built up it’s in-built calculator function within search by adding a visual interface with 34 buttons. If you search a sum, like 2+3, you used to be presented with the answer. But now with this feature you are given the answer with a calculator. The calculator includes functions for processing sines, cosines, and tangents as well as dedicated buttons for Pi and Euler’s number.
