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.

How do you solve algebraic expressions step by step?

There are several rules to consider. The main one is following the proper order of operations, using the PEMDAS rule. First you will need to remove parentheses, respecting the order of the operations. Then, you will have to reduce fractions and radicals as they appear in the expression. And then, you have to proceed somewhat recursively, as you go simplifying, because new simplifiable pieces may show up

Using this algebraic expression calculator you can compute simple stuff like the square root of 64, the absolute value of a number, or much more complex expressions like \(\sqrt(2^3/(1/2-1/3^{1/2}))\)
