Looking for a fun way to get better at doing math in your head? Working on new techniques to increase your math computation speed? This game keeps track of your best scores so you can track your improvement.
At the beginning of each round, 12 boxes appear containing various numbers. Choose an operator (+, -, ×, ÷), then select numbers in order to complete a correct equation. Correct answers will clear the 3 boxes. Clear all 12 before time runs out to finish the round.
The Options menu allows you to change difficulty settings for a variety of game play. Five difficulty levels are available: Very Easy, Easy, Medium, Hard and Very Hard. You can also select to have Addition/Subtraction, Multiplication/Division, or Both.
Your best score for each possible variation of options is saved so you can try to continuously beat your best.
How to Play:
• Select an operator (+, -, ×, ÷).
• Select numbers in order to complete a correct equation.
• A correct equation adds to your score and clears the boxes.
• Addition and Multiplication correct equations award 3 points.
• Subtraction and Division correct equations award 4 points.

• If there's open spots, you can select "Get New" to get a new number, but it will cost you 1 point.
• Clear all the boxes before time runs out and you win the round!
• Finishing the round faster will result in a higher time bonus score.
