Calculation Brain Training

This is a brain training game that you select and tap the one with the maximum answer from 6 formulas.

The score is determined by how many correct answers you get in 30 seconds.

If the answer is incorrect, the score will decrease.

If there are multiple maximum values, you can get points by tapping any of them.

The decimal point of the division answer is truncated.

You can turn off the sound by unchecking "Sound" in the menu item.

You can turn off vibration by unchecking "Vibration" in the menu item.

Studies have shown that brain training by simple calculation remains highly effective in activating the brain even after getting used to the same thing over and over again.
