Arithmetic Operations

Many times a programmer is given an algebraic formula, and must write an assignment statement that will correctly calculate the answer.
After writing a statement, check it by hand, using sample values verify that the equation is correct.
Use the following guidelines to convert algebraic expressions to programming statements:

Algebra	Program	Explanation
XY	x*y	Algebra uses single letters for variables, and can omit the *, programming languages always require an operator.
X·Y	x*y	Algebra sometimes uses a dot for multiplication.
	x*x or x^2	Use ^ to raise to a power.
	x^n	Use ^ to raise to a power.
	Math.Sqrt(x)	Use Math functions for square root. You will see others after you type Math.
	(a+b)/c	Compound numerators and divisors must be enclosed in parenthesis: Notice the difference between this example and the one below:
	a/c+b	Notice the difference between this example and the one above.

Remember: Algebra uses single letters for variables: programmers should use good variable names wherever possible!

That's all! Congratulations on completing all of the lessons in csharp!
