Mathematics

Handle addition, subtraction, multiplication, division, square root, and sign changes with memory keys, history, keyboard input, and fullscreen mode; no complex-expression parser.

Scientific calculator with trig, logs, exponents, powers, roots, factorials, permutations, combinations, memory, history, and DEG/RAD mode.

Enter 2x2 or 3x3 numeric square matrices by row for addition, subtraction, multiplication, transpose, determinants, and inverse.

Enter separate coefficients to solve ax + b = c or a 2x2 system, classify one/no/infinite solutions, and view numeric steps.

Enter a, b, and c for ax²+bx+c=0 to see real, repeated, or complex roots, the discriminant, axis, and vertex.

Calculate percentages, values, change rates, discounts, tax, tips, compound growth, and markup profit.

Solve supported three-side, side-angle, one-side-two-angle, and right-triangle inputs for sides, angles, area, perimeter, heights, and radii.

Derive radius, diameter, circumference, and area from one positive circle measurement, with clear length and square-unit distinctions.

Calculate rise, run, slope, y-intercept, distance, and a line equation from two distinct coordinate points, including horizontal and vertical lines.

Calculate dx, dy, Euclidean distance, Manhattan distance, and midpoint from two 2D Cartesian points, not geographic coordinates.

Round to 0-10 decimal places with round, ceiling, floor, truncate, and banker's modes, and view the original value and difference.

Calculate permutation and combination counts, binomial and Poisson point probabilities, expectation, variance, standard deviation, and coefficient of variation.

Calculate a single real number's absolute value, a basic |x| arithmetic expression, or the absolute difference between two numbers; no variables, functions, or complex modulus.

Enter a value, mean, and positive standard deviation to get a z-score, normal-model percentile, left-tail cumulative probability, and deviation category.

Find a hypotenuse, solve a missing leg, or check whether three positive side lengths satisfy the Pythagorean relationship.

Count significant figures and apply decimal-place or sig-fig rules to addition, subtraction, multiplication, and division.

Calculate the z statistic and two-tailed P value for a one-sample z test from a sample mean, null mean, population SD, and sample size.

Calculate the Greatest Common Factor (GCF/GCD) of two or more integers with shared factors and step-by-step work.

Calculate the least common multiple (LCM) of two or more integers with pairwise GCD/LCM steps and prime factor analysis.

Check primality, factor integers, count positive divisors, find neighboring primes, and list primes in an inclusive range.

Simplify, add, subtract, multiply, divide, or compare fractions using integer numerators and denominators.

Simplify integer ratios, scale equivalent ratios, and solve one missing term with ordinary numeric values in a proportion.

Enter non-negative integers to see quotient, remainder, the division identity, and a step-by-step decimal expansion; precision 0–12, without repeating-cycle detection.

Compute logarithms for any valid base, compare ln and log10, verify the change-of-base result, or evaluate a power directly.

Online math formula editor and LaTeX converter. Edit visually, paste source, sync MathML, download .tex/.xml, or export PNG; it is for layout, not evaluation or equation solving.

Evaluate numeric expressions with parentheses, powers, common functions, pi/e constants, implicit multiplication, and recent calculation history.

Calculate a percentage, A–F letter grade, and fixed 4.0-scale GPA from wrong answers, correct answers, or points. Adjust A/B/C/D cutoffs; no plus/minus, weighted, or curved grading.

Convert finite decimals to fractions and integer fractions to decimals, with automatic simplification and mixed-number output when applicable.

Convert non-negative integers between binary, octal, decimal, and hexadecimal, or apply binary arithmetic and AND, OR, and XOR operations with binary and decimal output.
