Algebra Solver & Calculator

lgebra Solver is a free math solver and scientific calculator that shows the actual working behind every answer, not just the result. You type a problem, press Solve, and read the solution one line at a time, the same way a teacher would write it on the board.

Everything runs on your phone. No account, no waiting for a server, and the math works offline, so you are not stuck hunting for an online scientific calculator every time the wifi drops. There are 19 tools inside, and every one of them explains its steps.

SOLVING AND ALGEBRA

The equation solver is an algebra calculator with steps that handles everything from linear and quadratic equations up to degree-10 polynomials. There is an inequality calculator that draws its answers on a number line, a systems of equations tool that solves up to 6 variables using Gaussian elimination, and a simplify and factor tool that expands, combines like terms and factors polynomials, decimals included. An absolute value tool with full branch analysis and an expression evaluator round things out.

CALCULATOR AND GRAPHS

The scientific calculator works with exact fractions instead of rounding everything off. Type 0.75 and it will happily work with 3/4. Trig, logs, roots, powers and variables are all there, plus 8 color themes if the classic look bores you. The graph plotter works like a graphing calculator and draws up to 3 functions at once; pinch to zoom, tap a curve to read exact coordinates. Calculus covers derivatives, integrals and limits step by step, and the matrix calculator gives you determinant, inverse, rank and A·x = b.

FRACTIONS, RATIOS AND CONVERSIONS

The fraction calculator takes fractions, mixed numbers or plain decimals and shows every result with visual bar models. It doubles as a decimal to fraction calculator and a fraction to decimal converter, and it can simplify fractions in one tap. The ratio calculator is a simple ratio solver: it reduces 12:18 to 2:3, compares ratios, and solves proportions like 3:4 = x:20, which also makes it handy as an aspect ratio or proportion calculator. The unit converter covers everyday metric conversion, from mm to inch and meters to ft through kilograms, pounds, Celsius and Fahrenheit, plus time, speed, area, volume, data, pressure, energy and angle.

NUMBERS AND PATTERNS

For number work there is a least common multiple calculator that finds the LCM and GCD (also labelled HCF or GCF, depending on where you went to school) with the Euclidean algorithm written out in full. A prime factorization calculator tests primality and lists divisors. The base converter turns binary to decimal, octal and hex step by step, and the modular arithmetic tool handles modular powers and congruences. Sequences and series covers arithmetic, geometric, quadratic and Fibonacci patterns, and statistics gives you mean, median, variance and quartiles with a histogram and box plot.

MADE FOR LEARNING

We built this for students who are tired of apps that spit out an answer with no explanation. Use it for homework, exam prep, or algebra for beginners starting from zero. The step by step solutions teach you the method, and if you only want the answer, you can switch explanations off in Settings.

Small things that make daily use nicer: a math keyboard with fractions, powers and roots one tap away, a history of everything you have solved, light and dark themes, and quick copy or share. The whole app supports the TalkBack screen reader, so equations, steps and graphs are read aloud for blind and low-vision students.

Algebra Solver is free and supported by ads.

If you ever wished your calculator would show its working, this is the one.
