Benefits of technology

This invention allows us to quickly solve problems by creating mathematical models based on various types of data such as time or distance between two points along an axis (linear equation). These solutions are faster than traditional methods like mathematic programming but still meet certain standards set forth in industry standard procedures. Additionally, this method saves energy because it does away from relying solely upon its own computational capabilities instead of requiring more powerful hardware components.
