1) a calculator that takes in two numbers and adds them
2) take two numbers and add, subtract, multiply, and divide
	a) check for zero; add "can't divide by zero" message
3) Quadratic formula (Ax^2 + Bx + C = 0): 
	a) get A, B, and C
	b) calcuate D = B^2 - 4*A*C (D for "determinant")
		i) if D < 0 then "no real roots"
		ii) if D == 0 then x = (your answer here)
		iii) if D > 0 then two roots; x1 and x2
	c) change 3bi to return the imaginary roots
	d) keep getting A, B, and C until the user enters 0 for A
		(then it's not quadratic any more)
4) take two aspirin and call me in the morning

- let us know how it goes.
