Instructions below tell how to use this page to solve equations or add and subtract fractions. For instructions on how to solve linear equations, see Purplemath tutorial.
Press Clear Problem to clear to enter a new problem.
Only linear equations are allowed, which means coefficients
and variables with +, -, and
= are accepted.
To use this as a fraction calculator, enter fractions in the problem box
as a simple equation, for example x=(1/4)+(1/5)+(3/7).
Parentheses and slash must be used for fractions, i.e. "one third" is
(1/3) and "two and a third" is 2+(1/3).
Press Make Solution if you do not have a solution to compute a solution.
Press Clear Solution to clear to enter your own solution with as many intermediate steps as you want to check and press Check Solution to check it.
Press Make Problem to get a sample algebra problem and press Less Variables, More Variables, Smaller Numbers, Bigger Numbers, Integer Solution, and Fractional Solution to adjust variables and values used in the sample.
