CalcMonkey is a free math website for kids, teens and adults. Younger kids practice addition, subtraction, multiplication and division with fun math games, then dress up their monkey and send it on adventures. Older students get step-by-step math help for algebra, geometry, trigonometry, calculus, statistics and linear algebra — with instant solvers and hands-on math games. There’s no sign-up needed.
Banana Grab, Balloon Pop, Jungle Race and Feed the Monkeys build fast math facts. Think-it-through games teach place value, carrying and borrowing, long division, fractions, order of operations and word problems.
Lessons by grade and topic with worked examples and unlimited practice problems: equations, slope, systems, quadratics, the Pythagorean theorem, logarithms, derivatives, integrals and more.
Type in your own homework problem and see every step: linear equations, the quadratic formula, systems of equations, lines, right triangles, derivatives and statistics.
Equation Builder, Shape Lab, Tangent Hunter and Area Hunter turn algebra, geometry and calculus into hands-on challenges.
