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

Count significant figures, round to 1–15 target figures with scientific notation and trailing zeros, or apply precision rules to two-number arithmetic.

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, convert, compare and calculate with fractions or signed mixed numbers. See exact reduced fractions, mixed forms and common denominators.

Divide a total into two or three ratio shares, allocate currency minor units exactly, simplify or scale ratios, and solve a missing proportion term.

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.
