Student Calculators
Use student-friendly calculators for grades, GPA, fractions, ratios, LCM, GCF, slope, quadratic equations, and scientific math.
MathFraction CalculatorCalculate, compare, simplify, and convert fractions or mixed numbers with exact steps.MathDecimal To Fraction CalculatorConvert terminating or parenthesized repeating decimals into exact simplified fractions with mixed-number form, reduction evidence, and notation checks.MathRatio CalculatorSimplify exact two-part or multi-part ratios, inspect shares and equivalent forms, distribute a total, or scale one part without rounding the entered relationship.MathProportion CalculatorSolve or verify any missing term in equivalent ratios, direct proportion, or inverse proportion with exact fraction and decimal input, constants, scale factors, and independent checks.MathLCM CalculatorFind the exact least common multiple of signed integers with prime-power evidence, divisibility checks, cycle multipliers, and boundary-case guidance.MathGCF CalculatorFind the exact greatest common factor of signed integers with common factors, prime-power evidence, grouping checks, and coprime analysis.MathSlope CalculatorAnalyze a straight line from two points, a point and slope, slope-intercept form, or standard form with exact equations, intercepts, angle, and geometry.MathQuadratic Formula CalculatorSolve exact quadratic equations with rational, irrational, repeated, or complex roots, then audit the discriminant, vertex, graph features, and root checks.MathFactoring CalculatorFind prime factors and integer properties, or factor an integer-coefficient quadratic when exact binomial factors exist.MathScientific CalculatorEvaluate scientific expressions with DEG/RAD trigonometry, logs, roots, powers, percentages, memory, history, and adjustable notation.StudentsGPA CalculatorCalculate term and projected cumulative GPA from named courses, grades, credits, prior GPA, and a future target plan.StudentsGrade CalculatorCalculate weighted grades, points-based totals, remaining-work targets, and the final exam score needed for a course goal.MathBinary CalculatorCalculate exact binary arithmetic, bitwise logic, shifts, and fixed-width signed or unsigned results with overflow checks and base conversions.
