App Description

I. this application is currently only product accumulation function.

II integration rule: Digital length X speed X (items X 2)

1, a digital length

Minimum 1 = 1 point, maximum 9 = 9 points, each additional bit on doubling

2, the speed (time digital display: milliseconds), the time, the higher the score;

Maximum 900 milliseconds (0.9 seconds) = 1 point, minimum 100 milliseconds (0.1 seconds) = 9 points

2, items (times, such as 12 X 33 X 65 in items 3)
1 items = 1 X 2 points
2 items = 2 X 2 points
3 items = 3 X 2 points
......

Third, the integral Example:

One, 5-digit, each 0.4 seconds, 4 items

5 × 6 × (2 × 4) = 240 points

Two, 3 digits, each 0.1 msec, 20 items

3 × 9 × (2 × 20) = 1080 points
