Algebra Calculators

Algebra homework tends to stall in the same places: an equation that will not rearrange, a matrix that will not resolve, or a log expression that looks different from the answer in the back of the book. The tools here work through those steps directly, showing the result for the values entered rather than explaining the topic in the abstract.

Pick a formula, tell the tool which value you are missing, and enter the values you know.

This Zero Calculator finds the zeros of a polynomial: the values of x that make the equation equal to zero, also called roots or x-intercepts.

Graphing an inequality means turning a statement such as y > x into a picture: a boundary line on a coordinate plane with every point that satisfies the inequality shaded on one side.

A radical like √72 or ∛250 is exact but hard to read, while its decimal (8.485 or 6.300) is readable but rounded.

An indicated variable is the letter an equation is solved for: in 2x + 5 = 15, x is indicated, and the answer is 5.

A three-step linear equation is a single equation with one variable, like 2(x + 3) = 18, that takes three moves to crack: clear the parentheses, move the numbers, then divide.

A system of three equations in three unknowns is the classic point where hand algebra starts to wobble: one sign slip in the elimination and the whole answer is wrong.

A log value is an exponent in disguise: log₁₀(1000) = 3 because 10³ = 1000.

Imaginary numbers stop being mysterious the moment you can push them through real arithmetic.

You already have the formula and the input value.
