Subject: [PATCH] Update BetterMaths.java

Refactor BetterMaths for Enhanced Readability and Error Handling

- Streamlined error handling with IllegalArgumentException for invalid range inputs.
- Consolidated redundant methods into `calculateRandomValue` for improved code maintainability.
- Simplified and clarified documentation and comments.
- Removed unused imports and optimized code structure.
