STANDARD & SCIENTIFIC

Perform arithmetic and scientific calculations with correct order of operations, parentheses, implicit multiplication, scientific notation, percentages, answer recall and M+, M−, MR and MC memory functions.

Use DEG/RAD, INV and HYP modes, trigonometric, inverse-trigonometric, hyperbolic and inverse-hyperbolic functions, logarithms, exponentials, powers, roots, factorials, permutations and combinations.

COMPLEX NUMBERS

Complex mode supports rectangular and polar forms, arithmetic, powers, roots, logarithmic, exponential, trigonometric and hyperbolic functions with principal-value results.

MATRIX CALCULATOR

Store MatA, MatB and MatC and work with 1×1 to 5×5 matrices.

• Addition, subtraction and multiplication
• Determinant, inverse and transpose
• Rank and trace
• Adjoint, cofactors and minors
• Integer matrix powers

STATISTICS & DATA ANALYSIS

Includes one-variable statistics with frequencies, linear regression, prediction, percentiles, z-scores, skewness, kurtosis and outlier detection.

Inference includes mean/proportion tests, paired samples, exact binomial and Fisher exact tests, confidence intervals, chi-square tests, one-way, two-way and repeated-measures ANOVA, including Welch ANOVA.

Normal, Binomial and Poisson probability tools are included.

Monte Carlo simulation supports Uniform, Normal, Lognormal, Binomial and Poisson models with reproducible seeds, percentiles, histogram, event probabilities and uncertainty estimates.

EQUATIONS & CALCULUS

Solve real-coefficient polynomials up to degree 5 and simultaneous linear systems with 2 or 3 unknowns.

Calculus includes symbolic differentiation, numerical derivatives, symbolic integration and adaptive definite integration with diagnostics.

Monte Carlo integration supports 1D, 2D and 3D regions, including constrained regions, reproducible seeds and uncertainty estimates.

ADVANCED GRAPHING

Plot up to four explicit or implicit functions with zoom, pan, equal-scale rendering, custom titles/axis labels, editable curve names, legend, grid/axis controls and 2400×2400 PNG export.

FINANCE, TABLE & BASE-N

Finance includes time value of money, loan amortisation, NPV, IRR, MIRR, payback, CAGR, bond valuation, duration, convexity and depreciation.

Table mode evaluates f(x) and optional g(x) over configurable ranges with up to 1,000 rows.

Base-N supports BIN, OCT, DEC and HEX; signed/unsigned 8/16/32/64-bit values; arithmetic; AND, OR, XOR, NOT and bit shifts.

ENGINEERING UNIT CONVERTER

Convert across 60 categories and 366 unit definitions covering mechanical, structural, thermal, electrical, magnetic, flow, molar, digital and general quantities. Selectors are searchable.

CURRENCY CONVERTER

Convert supported currencies using official NBU Open Data exchange rates. Includes search, swap, refresh, rate date and cached offline rates when available.

The entered amount and selected currency pair are not included in the NBU rate-table request; calculations are performed locally.

PRIVACY & OFFLINE USE

Core maths and conversion features are processed locally. No account, registration or sign-in is required.

Internet access may be used for Google AdMob, privacy/consent services and NBU exchange-rate retrieval. Most mathematical features work offline.
