Configuration

You can change how many 1s in an equation as well as the time for you to solve and the time for the whole game. The harder it gets, the more points you earn per correct answer.

How To Play

Try your best to get the right answer after solving the equation within the time limit until the game reaches the end.

The only operand/number is number 1 and the operators/operations are addition(+), substraction(-), multiplication(*) and division(/). The result can be Infinity or Underfined if there's a zero division.

You can play the game using keyboard. All the number key from 0 to 9 have been binded. For INF/UND button, the corresponding key would be the key to the right of the key 0 on the keyboard. (Key '-/_' on the horizontal line or Key "./Del" on numpad).

Equation Evaluation

For each equation, the final result is computed in the following ways:

1. Use absolute function abs() to make negative number into positive number.
2. If the new result is greater then 10, subtract it by 10.

Example:
Result = -0 (1)→ 0 (2)→ 0
Result = -4 (1)→ 4 (2)→ 4
Result = 11 (1)→ 11 (2)→ 1
