**Instructions:** Type any algebraic expression to evaluate, such as ‘2 + 3/4 + 3^2’ or ‘sin(3 pi) + 2cos(3 pi/2) + sqrt(2)’, etc., and the solver will compute the result for you

#### What is an Algebraic Expression?

An algebraic expression contains numbers, fractions, trigonometric functions, exponential functions, powers and roots. An example of an algebraic expression is shown below

\[\frac{1}{3-2}+ 3 + 4\sin(\frac{\pi}{4}) + \sqrt{2} + 5^{\frac{3}{2}}\]For an algebraic expression calculator to work, it is typically required to type the above type of math expression in, by using common symbols. For example, the above expression would be expressed as “1/(3-2) + 3 + 4sin(pi/4) + sqrt(2) + 5^(3/2)”. The most important thing to keep in mind is that the parenthesis are important when typing an algebraic expression.

For example “1/(3-2) + 3 + 4sin(pi/4) + sqrt(2) + 5^(3/2)” is not the same as typing “1/3-2 + 3 + 4sin(pi/4) + sqrt(2) + 5^(3/2)”. The latter expression would be understood by the solver as

\[\frac{1}{3} – 2+ 3 + 4\sin(\frac{\pi}{4}) + \sqrt{2} + 5^{\frac{3}{2}}\]and not as

\[\frac{1}{3-2}+ 3 + 4\sin(\frac{\pi}{4}) + \sqrt{2} + 5^{\frac{3}{2}}\]and you would be getting an unwanted outcome, and not the one you intended. So use parentheses wisely to group terms that you intend to group.
