Algebra & Equations

The algebra tools solve equations and find the solutions themselves. Just enter the coefficients and right-hand sides, and you can follow the working step by step, right down to which equation was multiplied by what and subtracted from which.

From checking answers to two-unknown systems taught in school to verifying linear algebra and physics problems with three or more unknowns, please use them wherever hand calculation is prone to mistakes.
