Math Calculators
From homework to spreadsheets — fast tools for percentages, fractions, equations, geometry and statistics.
Math Without the Friction
Most math questions in adult life don't need a research paper — they need an answer. What is 15% off $89.99? What is 3/4 plus 2/5 as a decimal? What are the roots of x² − 5x + 6? These calculators get you there in seconds, with the steps shown so you can learn the why, not just the what.
What's Included
The percentage calculator handles all five classic percentage problems. Fraction does arithmetic and reduces to lowest terms. Quadratic equation returns real or complex roots, the discriminant and vertex. Triangle solves any triangle from three knowns. Statistics gives you mean, median, mode, standard deviation and variance. GCF & LCM handles common-factor problems. Random number generator and a full scientific calculator round out the section.
Show Your Work
Each calculator displays the formula and intermediate steps so they double as teaching tools. If you're helping a student, the page itself acts as a worked example.
