Mathex Lite Calculator 1.3.0

The Mathex Lite Scientific Calculator offers a comprehensive, expression-based interface that closely mimics the operation and appearance of a physical scientific calculator. As a free version of the full Mathex application, it provides essential functionalities suitable for various mathematical tasks.

Features include:

• Direct algebraic input: enter equations as they are written
• History playback: review the last 10 calculations performed
• Expression editing: modify equations and recalculate as needed
• Chain calculations: incorporate previous answers into new equations
• Two-line display: simultaneously view equations and results
• Basic plotting capability (limited in Lite edition)
• Symbolic derivatives (locked in Lite edition)
• Metric conversions and physical constants table
• Ten numerical memory slots
• Percentage calculations and combinatorial operators
• Trigonometry functions adjustable for degrees, radians, or grads
• Multiple display modes including Normal, Fixed, Scientific, and Engineering
• Digit grouping according to SI/ISO standards with thin space separators
• Random number generator including white noise
• Robust and user-friendly design

The Lite version is supported by advertisements, which are hidden during actual calculator use. While visually identical to the full version, certain features are restricted or limited:

• Locked features: symbolic derivatives and tangent line plotting
• Usage limitations: plot executions capped at 10 per day, 30 per week; expression evaluations limited to 25 daily (reducing to 8 after the first week) and 120 weekly (reducing to 40 after the first week)
• Additional minor limitations include less frequent backend updates compared to the full version

All restrictions can be lifted by purchasing the full version of Mathex, which unlocks all features and supports ongoing development—costing equivalent to a coffee.
