How to Use the Math Calculators
Select Calculator
Choose from Quadratic, Systems, Polynomial, Logarithm, or Factorial.
Enter Values
Provide the required inputs for your selected calculator.
Get Results
Instantly see the results with step-by-step solutions.
Quadratic Equation Solver
Solve quadratic equations of the form ax² + bx + c = 0. Enter coefficients a, b, and c to find real and complex roots.
Step 1: Calculate discriminant: Δ = b² − 4ac = (-5)² − 4(1)(6) = 25 − 24 = 1
Step 2: x = (−b ± √Δ) / 2a = (5 ± 1) / 2 → x = 3, 2
System of Equations Solver
Solve systems of linear equations. Enter coefficients for 2×2 or 3×3 systems and get the solution.
Step 1: Solve using elimination or substitution.
Step 2: 2x + 3y = 8, 3x + 2y = 7 → x = 1, y = 2
Polynomial Calculator
Add, subtract, multiply, or divide polynomials. Enter polynomial expressions and choose an operation.
Logarithm Calculator
Calculate logarithms in any base. Enter the base and the argument to find the logarithm.
Formula: log_b(a) = x → b^x = a
Calculation: log₁₀(100) = 2 because 10² = 100
Factorial Calculator
Calculate factorials, permutations, and combinations. Enter n and r values to compute results.
Formula: 5! = 5 × 4 × 3 × 2 × 1 = 120
nPr: 5P3 = 5!/(5-3)! = 120/2 = 60
