[Requirement] Button Calculator

Hello, I am software developer Wonjohn Choi.
What we are going to make now is a calculator.
This calculator will be a really simple calculator called “Button Calculator.”
Here is the general information.
  • Requirement: Calculator will contain buttons: 0,1,2,3,4,5,6,7,8,9, (.), +, -. *, /, =, ^, sin, cos, asin, acos, tan, atan, sqrt, cbrt, PI, E. Whenever an user clicks a button, a value is calculated. This calculator does not support calculating an equation. For example, if user clicks 169 and sqrt, calculator will directly give 13 as output.
