SumWise 2.2.0 Release Notes

SumWise 2.2.0 is a Windows desktop update focused on improved symbolic algebra, scoped polynomial workflows, visual calculus helpers, better exact/fraction result workflows, history and copy polish, helpful error suggestions, and safer everyday input handling.

What Is New

expand(...) and simplify(...) add safe deterministic symbolic algebra helpers.
factor(...), roots(...), and solve(...) are improved for supported polynomial workflows.
tangent_line(...), definite_integral(...), critical_points(...), and extrema(...) expose scoped visual calculus helpers for supported polynomial cases.
fraction(...), mixed(...), approx_fraction(...), and approx_mixed(...) improve exact, mixed-number, and approximate fraction workflows.
Copy Result, Copy Exact, Copy Mixed, and output history copy/reuse actions make it easier to move results where you need them.
Helpful error suggestions point common mistakes toward likely next steps without changing the calculator's offline behavior.
Unit conversion accepts more natural input forms, including no-space examples such as 100km/h to mph, while keeping unsupported units safe.

Symbolic Algebra And Polynomial Workflows

SumWise 2.2 strengthens supported symbolic math with scoped, deterministic helpers for common algebra and polynomial cases. The goal is practical reliability: supported expressions should expand, simplify, factor, solve, or report limitations clearly.

Example workflows include expand((x+2)(x+3)), simplify(2*x + 3*x), factor(x^2 + 5*x + 6), and solve(x^2 = 4, x).

Visual Calculus Helpers

The new visual calculus helpers expose useful polynomial workflows directly from the calculator. They are scoped to supported univariate polynomial cases rather than broad symbolic calculus coverage.

tangent_line(x^2, x, 2)
definite_integral(x^2, x, 0, 3)
critical_points(x^2 - 4*x + 4, x)
extrema(x^2 - 4*x + 4, x)

Result And Input Polish

Fraction and mixed-number workflows are easier to use in 2.2. Exact and Mixed secondary results can appear when useful, and explicit approximate helpers are available when a decimal needs a denominator-limited fraction.

convert(100, km/h, mph)
100km/h to mph
fraction(1000/60)
mixed(1000/60)
approx_fraction(0.3333333333)

Output history actions and copy controls make it easier to reuse previous inputs and copy the result form you actually want.

Notes And Cautions

SumWise 2.2.0 is a Windows desktop release.
Symbolic math is scoped to supported algebra, polynomial, and calculus cases, not every general-purpose symbolic algebra workflow.
Visual calculus helpers are currently focused on supported polynomial workflows.
Function Reference coverage depends on available metadata, so some functions have more detail than others.
SumWise is not an exam-certified handheld calculator.
