A high-intensity drill to boost arithmetic speed and accuracy. This tool is highly configurable, allowing users to select operation types, set the difficulty level by defining the range of numbers, and choose the duration of the drill. As the user answers questions, a real-time score is updated. When the timer runs out, a summary screen displays the final score and accuracy percentage. This is a fantastic tool for students to practice for timed tests and for anyone looking to keep their math skills sharp.
