Welcome to the Calculation League Simulator!

Here are some instructions on how to use the simulator:

1. Select the mode and number of questions or the desired time. If you choose to select a time, you do not need to set the number of questions.
2. Answer each question within the 30-second time limit.
3. "Toggle text direction" button will switch between "left to right" and "right to left" text direction when answering.
4. For non-integer answers, two significant digits are required for answers between -100 and 100, and the nearest integer is required for answers less than -100 or greater than 100.
5. The simulator will move to the next question upon a correct answer or expiration of 30 seconds.
6. The number of correct answers and time taken are displayed on the bottom left and right of the screen.

Good luck!
