Study tools

Calculate clearly. Graph boldly.

Explore exact algebra, unit conversions, statistics, matrices, and introductory calculus—then make functions visible in the graphing workspace.

Symbolic & numeric calculator

Work the idea, then check the answer.

Arithmetic, fractions, radicals, powers, percentages, complex numbers, and exact simplification.

Use * for multiplication, ^ for powers, sqrt() for radicals, and radians for trigonometry.

Your result will appear here.

Exact forms stay exact until you ask for a decimal.

Unit converter

Move between measurement systems.

Choose a category and convert common metric or US customary units. Fractions such as 3/4 are accepted.

Your conversion will appear here.

Exact ratios stay as simplified fractions where useful.

Graphing calculator

See how the function moves.

Plot several functions, inspect values, and use numerical calculus tools. Drag to pan and use the mouse wheel or trackpad to zoom.
