The Uncertainty Calculator enables users to perform calculations using precise numbers and ranges (e.g., 4 or 4 ± 6) to express uncertainty. It simplifies statistical reasoning for everyday decisions, helping users gauge potential financial outcomes in uncertain situations.

= Key Features
* Input both exact numbers and ranges with a tilde (~) to denote uncertainty.
* Operates on basic mathematical operations: addition, subtraction, multiplication, and division, and supports functions like exponentiation, square roots, and trigonometric functions.
* Utilizes a Monte Carlo method for computations, providing a probabilistic range of results.
* Design is basic and intentionally user-friendly, aiming to empower those without deep statistical knowledge.

= Limitations
* Calculation speed is slower due to Monte Carlo simulations, and the formula parser may show errors.
* Only normal distributions are assumed for ranges, providing a simplified model for uncertainty.

= Practical Applications
* Estimate financial viability of business ideas, calculate potential investment returns, assess risks, and more, all accounting for uncertainty in key variables.
