SumWise 2.4.0 Release Notes

SumWise 2.4.0 is a Windows desktop correctness, reliability, and responsiveness update focused on stronger exact simplification for eligible expressions passed directly to simplify(...).

Stronger Exact Simplification

• Eligible homogeneous same-monomial sums with two through seven physical additive terms can use the strengthened exact behavior.
• Supported signed integer and rational coefficients are combined deterministically.
• Supported positive integral powers and multi-symbol monomials such as y^2 and a*b^3 are preserved.

simplify(2*x + 3*x) -> 5*x
simplify(x + 2*x + 3*x) -> 6*x
simplify(3*x/2 + x/2) -> 2*x

Conservative Compatibility

The new exact behavior applies only when an explicit simplify(expression) input is conservatively eligible. Unsupported or uncertain forms, heterogeneous or mixed terms, nonadjacent repeated groups, cancellation, one-term inputs, and expressions with more than seven physical additive terms continue through the established simplifier.

Inputs with more than seven physical additive terms remain supported rather than being rejected. Existing behavior such as simplify(x - x) -> 0 is preserved, and the update does not route every expression or every simplify(...) input through the new bounded behavior.

Reliability And Responsiveness

Reliability work strengthens deterministic results and conservative fallback for the supported workflow. Two through four eligible homogeneous terms are expected to be responsive. Five eligible terms may produce a noticeable subsecond synchronous calculation, while six or seven may create a brief synchronous wait. Timing depends on the computer and current system load. This release does not add asynchronous evaluation or a progress indicator.

Current Scope

SumWise 2.4 supports practical scientific computation, interactive graphing, exact results, statistics, regression, matrices, vectors, units, and supported symbolic algebra and calculus workflows. It does not claim universal general-purpose CAS coverage or support for every equation type.

Historical release

SumWise 2.3.0

SumWise 2.3 was a Windows desktop update focused on making graphs easier to explore and share while adding the Microsoft Store trial, license, localized-price, and purchase experience for the coordinated 2.3 launch.

Graph Inspection And Interaction

• Hover near a visible plotted curve to inspect its function label and approximate coordinates.
• Click an inspected curve point to keep its coordinate pinned while you continue exploring.
• Copy a pinned coordinate in a compact, reusable text format.
• Hidden functions and discontinuity gaps remain excluded from curve inspection.
• Existing graph pan, wheel zoom, reset, visibility, and overlay behavior remains available.

Graph Copying, Export, And Visible Controls

• Copy the current graph directly as an image.
• Save a clean, high-resolution PNG of the visible graph.
• Use visible controls for zoom in, zoom out, reset, image copying, and PNG saving.
• Graph exports include the current viewport, visible curves, supported overlays, and a persistent pinned point when present.
• Transient hover state and surrounding application controls are excluded from exported graph images.

Microsoft Store Trial And Purchase Experience

• Try every SumWise feature during a full-featured seven-day Microsoft Store trial.
• See calm, clear trial and license status inside the application.
• View the localized price supplied by Microsoft Store where purchase is available.
• Purchase through Microsoft Store and unlock only after the paid entitlement is verified.
• Continue using the verified public scientific, graphing, symbolic, calculus, statistics, matrix, vector, and unit-conversion feature set.

SumWise 2.2.0

Version 2.2 introduced improved supported symbolic algebra, scoped polynomial workflows, visual calculus helpers, exact and mixed result workflows, history and copy polish, helpful error suggestions, and more natural unit-conversion input.

• expand(...) and simplify(...) added deterministic helpers for supported symbolic cases.
• factor(...), roots(...), and solve(...) improved supported polynomial workflows.
• tangent_line(...), definite_integral(...), critical_points(...), and extrema(...) added scoped visual calculus helpers.
• Exact fractions, mixed-number results, history reuse, copy controls, and unit conversion input received workflow improvements.

Historical release

SumWise 2.1.0

Version 2.1 focused on usability, learning, discoverability, and practical unit conversion while preserving the existing scientific, graphing, symbolic, statistics, matrix, vector, and constants workflows.

• Guidance Modes let users choose how much in-app help appears while they work.
• The Function Reference added richer syntax, examples, argument details, return information, notes, and related learning material where available.
• Learning Paths, Try Next suggestions, contextual argument hints, and session Favorites improved discovery and reuse.
• Unit conversion expanded across practical categories with unit-aware results and natural-language inputs such as 100 km/h to mph.

Historical release

SumWise 2.0.0

Version 2.0 established SumWise as a broader Windows scientific computation platform rather than only a calculator.

• Scientific calculation, variables, exact results, constants, and unit conversion shared one desktop workspace.
• Interactive graphing, supported symbolic math, and visual calculus foundations were introduced together.
• Statistics, regression, vectors, matrices, and complex numbers became native workflows.
• The Welcome dashboard, autocomplete, persistent settings, and metadata-powered Function Reference improved discovery.
