CalcVert: Calculator Converter

CalcVert combines a calculator, scientific calculator, graphing calculator and unit converter in one clean, easy-to-use app for everyday math, school, study and work. Solve equations, inequalities and systems with step-by-step solutions, use advanced math functions, plot interactive graphs, convert units and currencies, and understand how calculations work.

Equation & Inequality Solver

Solve linear, quadratic, rational (fractional) and higher-degree equations and inequalities, depending on the expression. Get clear results in mathematical notation, with detailed solution steps to help you understand the process.

• Step-by-step solutions
Follow the reasoning behind each problem. For supported expressions, explore multiple solution methods, including sign analysis, isolating squared terms and the quadratic formula (discriminant).

• Solution sets
View inequalities using interval notation and equivalent conditions, such as:

(-∞, -3/2] ∪ (-1, 1)

or x ≤ -3/2 or -1 < x < 1.

• Systems solver
Solve systems with two or more expressions, including equations and inequalities, with steps for supported problem types.

Calculator

• Everyday calculator
Perform addition, subtraction, multiplication and division with an intuitive interface.

• Scientific calculator
Calculate powers, custom exponents, square and cube roots, nth roots, reciprocals, logarithms (log and ln), and expressions with π and parentheses.

• Trigonometry
Use sin, cos, tan, arcsin, arccos, arctan, sinh, cosh and tanh in degrees or radians.

Graphing Calculator

Plot and analyze functions and conic sections, including lines, parabolas, circles, ellipses and hyperbolas. Display multiple equations on the same Cartesian plane.

• Graph analysis
Explore intercepts, intersections, vertices, foci, axes, directrices, minimum and maximum points, asymptotes, symmetry and other curve properties.

• Dynamic parameters
Enter equations with variables, such as y = mx, and change parameter values to see the graph update as a line rotates or a curve changes.

• Graph recognition
Identify supported graph or equation types in the current view and inspect detailed properties.

Projects and Export
