CAS features

Symbolic simplification

Simplify algebraic expressions, combine like terms, and reduce fractions automatically.

Equation solving

Solve linear, quadratic, and polynomial equations. Get exact symbolic answers, not just decimals.

Factor & expand

Factor polynomials into irreducible components or expand products into standard form.

Function graphing

Visualize functions with interactive graphs. See roots, intercepts, and behavior at a glance.

Example problems

x^2 + 3x + 2Simplify an expression solve(x^2 - 5x + 6 = 0, x)Solve a quadratic factor(x^3 - 8)Factor a difference of cubes expand((x+2)(x-3))Expand a product diff(x^3 + 2x, x)Differentiate 3x + 5 @ x=7Evaluate with substitution

Graphing capabilities

Plot polynomial, rational, and trigonometric functions

Identify roots, intercepts, and asymptotes visually

Compare multiple functions on the same graph

Interactive zoom and pan controls
