SPOKEN MATHEMATICS Every calculation produces a spoken description in natural language. Results are read in English, French, and German, covering fractions, roots, powers, integrals, and more - exactly as a teacher would say them. DISPLAY FORMATS Results appear as rendered mathematics: exact fractions, square roots, pi-forms, scientific notation, mixed numbers, prime factorisation, and degrees-minutes-seconds. Toggle between exact and decimal form instantly. WHAT MATHEA CAN CALCULATE • Arithmetic: fractions, powers, roots, factorials, percentages, GCD, LCM, integer division with remainder, powers of 10 entry • Functions: sin, cos, tan and inverses; log, ln, log base n; 10^x, e^x; square root, cube root; nPr, nCr; Abs, integer part, rounding; random number, random integer • Calculus: definite integral, derivative, summation, product • Complex numbers: full arithmetic, magnitude, argument, real and imaginary parts, conjugate; rectangular and polar display • Base-N: binary, octal, decimal, hexadecimal; bitwise NOT, AND, OR, XOR, shift • Matrices: up to 4x4; addition, subtraction, multiplication, scalar multiplication, transpose, determinant, inverse • Equation solver: simultaneous linear equations (2x2, 3x3, 4x4) • Polynomial solver: quadratic and cubic equations • Inequality solver: linear and quadratic inequalities • Statistics: one-variable and two-variable analysis; 8 regression models (linear, quadratic, cubic, quartic, logarithmic, exponential, power, inverse) • Distributions: normal, binomial, Poisson - probability density, cumulative distribution, and inverse • Function table: evaluate f(x) and g(x) over any range with any step size • Ratio solver: A:B = X:D or A:B = C:X • Verify mode: evaluate relational expressions (equal, not equal, less, greater, etc.) to True or False • Coordinate conversion: polar to rectangular and back • Angle units: degrees, radians, gradians with inline suffixes MEMORY AND USER FUNCTIONS Store values in variables A through F, x, y, z.
