Algebra to code

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	There is no way to type a smaller exponent.
	pow(x,n)	Use #include <math> for power function.
	sqrt(x)	Use #include <math> for square root function.
	(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!
