# One page example is a Chrome dinosaur game derivative. While running without colliding, if the speed is below 13, it starts at 6 and increases by 0.001 per update.

One page example is a Chrome dinosaur game derivative. It extracted the rule that while running without colliding, if the speed is below 13, it starts at 6 and increases by 0.001 per update.

The other is about why 200 + 10% equals 220 in the Windows Calculator. The % after addition calculates the percentage of the preceding number, adding 20, while after multiplication, 10% becomes 0.1.

It examined the installed Calculator 11.2508.4.0 with REA 4.1.0, and the inference sentences are marked as examples.

The README also contains a statement to use it for legitimate purposes and that the user should handle necessary permissions.

## Original README

페이지 예시 하나는 크롬 공룡 게임 파생판이야. 부딪히지 않고 달리는 동안 속도가 13 아래면 6에서 시작해 업데이트마다 0.001씩 오른다는 규칙을 꺼냈어.

다른 하나는 윈도우 계산기에서 200 + 10%가 왜 220인지야. 더하기 뒤의 %는 앞 숫자의 퍼센트를 구해서 20이 붙고 곱하기 뒤에선 10%가 0.1이 된대.

설치된 계산기 11.2508.4.0을 REA 4.1.0으로 들여다본 건데 추론 문장은 예시용이라고 표시돼 있어.

합법적인 용도로 쓰고 필요한 권한은 사용자가 챙기라는 문구도 README에 있어.
