Read full description

Vectron is a complete mathematics toolkit, covering everything from quick everyday arithmetic to university level analysis, all in one app. A Basic Calculator for everyday arithmetic. Vectron Calc, a full scientific calculator that works across real numbers, complex numbers, exact fractions, and different number bases in a single tool. A Unit Converter covering scientific and everyday units. A Statistics Calculator for mean, median, mode, and more. A dedicated workspace with tabs for Equations, Matrices, Complex Numbers, Systems of Equations, Function Analysis, a 2D Function Plotter, and a 3D Plotter that draws any function of x and y as a rotatable surface you can drag to view from any angle. Analysis Calc solves derivatives, integrals, and limits across polynomial, rational, exponential, logarithmic, trigonometric, radical, and other function families, every result shown with full step by step reasoning, not just a final number. A dedicated Differential Equations solver handles first and second order equations the same way. 3D Geometry computes volume and surface area across common and advanced solids, shown as a rotatable model that stretches to match your inputs. Set Operations covers GCD, LCM, primes, and modular arithmetic. A Proportions tool handles ratios and direct or inverse variation. A Math Formulas reference guide, a Multiplication Table for interactive practice, a Unit Circle explorer, and a Math Keyboard for typing and exporting equations with special mathematical symbols. Five guided Learning Worlds, Algebra, Geometry, Analysis, Trigonometry, and Probability, take you through levels in order. Every single question comes with a full explanation, not just a correct or incorrect mark, so a wrong answer becomes something you understand rather than just try again. Play against Vectron head to head, or watch it play itself. Every match is saved to a full history so you can reopen and review any game, move by move. Practice at your own pace with KenKen Master, Prime Strategy, and CrossMath, three logic and number puzzle modes built for solo play, each with its own progression separate from the PvP arena. Step into head to head matches and race another player live. Math Duel tests raw speed calculation, KenKen Race and CrossMath Duel turn logic puzzles into a real-time race, and Prime Strategy Duel rewards tactical thinking under a clock.
