Advanced mathematics calculator with graphing, matrix operations, and statistics. Free TI-84 alternative for students - no more $100+ calculators needed!
Our advanced scientific calculator provides all the features of expensive TI-84 calculators for free. Calculate trigonometry, logarithms, plot functions, perform matrix operations, and analyze statistics online. Perfect for high school, college, and university students studying algebra, calculus, physics, chemistry, and engineering.
Better than Desmos (limited functions) and Wolfram Alpha (requires $5/month). Completely free forever with graphing, matrix algebra, statistics, and scientific functions. Works offline once loaded - no app download required.
A full scientific calculator in your browser: trigonometry (degrees/radians), logarithms, exponents, factorials, permutations and combinations, complex numbers, unit conversion and a history tape — plus a graphing mode for plotting functions, a matrix calculator and statistics (mean, median, standard deviation, regression).
Keyboard-friendly and free, it covers school, engineering and college maths without installing an app, and shows step-by-step evaluation for expressions.
Yes — toggle DEG/RAD; the mode applies to sin, cos, tan and their inverses.
Enter an expression in x (e.g. x^2 − 3x + 2) in Graph mode to plot it, zoom, and read intercepts and turning points.
Yes — add up to 4×4 matrices for determinant, inverse, transpose, addition and multiplication.
It uses IEEE double precision (about 15 significant digits) like handheld scientific calculators; check your exam board's rules on online tools.
Yes — digits, operators, parentheses, Enter for equals and Backspace to delete.
