Calculator - It just calculates
A device that is used for doing calculations.

The plainest app among the others, there isn't much we can talk about Calculator, what it does is just calculate, that's it. There is a History page which displays all your past calculations you had did on the app, you can clear it if you'd like to.

Anyway, let me leave some of the most common Maths formulas you can use in the Calculator app (make sure to use DEG):
• sin30 = 0.5 or sin-1(0.5) = 30
• cos60 = 0.5 or cos-1(0.5) = 60
• ln(e) = 1
• log100 = 2
• ln(8) ÷ ln(2) = 3
• e = 2.71828 (Euler's number)
• π = 3.14159 (Pi)
