Simplify expressions, factor polynomials, expand products, and solve supported equations.
Keep exact symbolic math beside the graph.
Callie Pro's CAS handles supported algebra and calculus operations while preserving a readable history of expressions and results.
When an exact result becomes a visual or numerical question, graphing, Table, Trace, Matrix, and local Python tools stay in the same app.
$2.99 one-time purchase in the U.S. App Store.

Work with exact expressions.
Use supported simplify, factor, expand, solve, derivative, integral, limit, and substitution operations without forcing every result into a floating-point approximation.
Differentiate, integrate, and evaluate supported limits.
Review previous operations and results while the structure of the session is still visible.
Choose a useful result format.
Result controls make symbolic output easier to read and carry into the next part of the problem.
Continue into another workspace.
Move to graphing, Table, Trace, Matrix, or Python when exact structure needs visual or numerical follow-up.
Choose one symbolic operation and inspect its exact result.
Enter the expression in CAS, choose simplify, factor, expand, solve, derivative, integral, limit, or substitution as supported, and review the history before carrying the result into Graph or Python.
Keep exploring the math.
