Currently, you can test your Math skills on the main 4 operations: Addition, Substruction, Multiplication, and Division, with or without negative numbers.
You start each game from the 1st level and progress higher as your correct answers are 8 more than your mistakes.
Each level is the same but with slightly higher numbers.
You need to finish each level in a certain amount (You can now turn time off if you choose)
You can click the CORRECT or WRONG numbers to see your mistakes.
Enjoy!
