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:
|XY||x*y||Algebra uses single letters for variables, and
can omit the *, programming languages always require an
|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
Remember: Algebra uses single letters for variables: programmers should use good variable names wherever possible!
