Solutions will be available when this assignment is resolved, or after a few failing attempts.
Build a calculator using only static and class methods.
This is the way it should work:
Calculator.add(2, 4) # 6 Calculator.subtract(8, 1) # 7 Calculator.multiply(3, 5) # 15 Calculator.divide(5, 2) # 2.5
Note that I've never created an instance of the calculator. I'm using the regular class.
One final addition. The
subtract method must be implemented using the
add method. Something like this:
subtract = add(x, y * -1)
