Algebraic Calculators — All-in-one
Instant, client-side algebra tools: squares, cubes, roots, quadratic & cubic solvers, exponents, logs, percentage converters and more — all responsive and accessible.
Square Calculator (x²)
Quickly square any number. Useful for algebra and geometry.
Cube Calculator (x³)
Cube numbers for volume formulas and algebraic expressions.
Square & Cube Roots
Compute principal square root or cube root. Handles negatives for cube root.
Quadratic Formula Calculator
Solve ax² + bx + c = 0. Returns exact real or complex roots.
Completing the Square
Rewrite ax²+bx+c as a(x+h)²+k and show steps (a≠0).
Cubic Equation Solver (numeric)
Solve ax³+bx²+cx+d = 0 numerically. Uses multiple starts & deflation to find up to 3 roots (real/complex).
Difference of Two Squares
Factor expressions of form A² − B² into (A−B)(A+B). Enter A and B (numbers or expressions).
Dot Product Calculator
Compute the dot product of two vectors (comma-separated numbers).
Exponents & Large Exponents
Compute x^y. For very large integer exponents the BigInt path is used when values are integers.
FOIL Method Calculator
Multiply two binomials (ax + b)(cx + d) and show the expanded result.
4th, 5th & Fractional Exponents
Compute x^(1/n) or x^p where p is fractional (e.g., 2^(3/2)).
Logarithm Calculator
Compute log base b of x. Common bases available.
Percentage Calculators
Change, increase, decrease, difference and percent error calculators useful for algebra and finance.
Perfect Cubes — First 100
List of the first 100 perfect cubes (n³). Handy reference for cubic problems.
Radical Simplifier
Simplifies √(n) into k·√(r) with integer k and smallest r.
