    How does the Math Solver work?

    The MultiIdeasWeb Solver is a free educational tool that analyzes your problem, automatically detects the type (arithmetic, fraction, linear, quadratic or exponential equation) and applies the correct algorithm showing each intermediate step with explanations.

    Problem types it can solve

    🔢 Arithmetic

    600+730+3!

    Add, subtract, multiply, divide and factorial with integers and decimals.

    ➗ Fractions

    4/5 + 3/10

    Operations with fractions, common denominator, simplification.

    📈 Linear

    2x + 3 = 15

    First-degree equations with unknown x. Step-by-step solving.

    📐 Quadratic

    (x+2)(x-3)=0

    Second-degree equations. Discriminant, general formula, factoring.

    ⚡ Exponential

    3^(x+1)=81

    Equations with x in the exponent. Logarithms and numeric bisection.

    ❗ Factorial

    5! + 100

    Factorial (n!) computation for combinatorics and probability.

    🧬 KEY FORMULAS

    Reference math formulas

    Quadratic equation (general formula)

    To solve ax² + bx + c = 0: x = (-b ± √(b²-4ac)) / (2a). The discriminant Δ = b²-4ac tells us how many solutions exist.

    • Δ > 0 — Two distinct real solutions
    • Δ = 0 — One double real solution
    • Δ < 0 — No real solutions (complex)

    Exponential equation with logarithm

    For a^x = b: log both sides gives x·log(a) = log(b), so x = log(b) / log(a).

    Factorial

    The factorial of n, written n!, is the product of all positive integers up to n. Example: 5! = 5·4·3·2·1 = 120.

    Adding and subtracting fractions

    For a/b ± c/d: use common denominator. Result: (a·d ± c·b) / (b·d), then simplify with GCD.

    💡 HOW TO LEARN

    How to leverage the Solver to learn

    The tool works best when you use it to understand the process, not just copy the answer. Best practices:

    • Try the problem first — Write your process on paper before checking the steps here.
    • Compare step by step — Find where you got stuck or made an error.
    • Note the formulas — Handwrite key formulas: quadratic, factorial, log. Muscle memory helps.
    • Practice with worksheets — Complement with printable worksheets to reinforce offline.
    • Export your solution as PDF — Save the steps to review before a test.
    • Use OCR for homework — Take a photo of textbook problems instead of typing.

    ❓ FAQ

    Frequently asked questions

    What kind of problems can this solver handle?
    It solves arithmetic with integers, decimals and fractions, factorial expressions, powers, linear, quadratic and exponential equations. Shows all intermediate steps.
    How does the OCR feature work?
    The OCR button uses Tesseract.js to recognize text from an image. Works best with sharp, well-lit photos and neat handwriting.
    Can I export the solution as PDF?
    Yes, the Export PDF button downloads the complete solution with all steps and final result.
    How is a quadratic equation solved?
    Use the formula x = (-b ± √(b²-4ac))/(2a). The discriminant tells if there are two, one, or no real solutions.
    Is it really free with no sign-up?
    Yes, 100% free and no sign-up. All processing happens in your browser.
    What is factorial and how to compute it?
    The factorial of n, n!, is the product of all positive integers up to n. Example: 5! = 120.
    How is an exponential equation solved?
    Apply logarithms. For a^x = b: x = log(b)/log(a). For mixed cases we use numerical bisection.
    Can I use it for homework?
    The goal is to learn by seeing the steps. Best use: try on paper first, then verify here. Complement with our printable worksheets.
