수학·과학 기호를 버튼이나 단축키로 입력한 뒤, 복사해서 원하는 곳에 붙여넣으세요.
Ctrl 단축키로 더 빠르게 입력할 수 있습니다. 예: Ctrl+A를 누를 때마다 α → ∧ 순서로 바뀝니다. 버튼에 마우스를 올리면 단축키가 보입니다.
문자 사용 안내
x ≤ 5 · a ≠ b · 2 × 3
비슷한 모양의 문자를 구분하세요. ×는 곱하기, x는 문자이며 −와 하이픈도 다릅니다. 기호를 입력하는 것과 수식을 계산하는 것은 별개이며, 붙여 넣는 수식 편집기의 입력 형식을 확인하세요.
이 키보드로 입력하기
- 입력창에 일반 글자를 적고, 기호를 넣을 위치에 커서를 놓으세요. 이 키보드에서 입력할 수 있는 문자의 예: ⟨ · ⟩ · ⟦ · ⟧ · ⌊ · ⌈.
- 원하는 문자 버튼을 누르세요. 대문자 짝이 있는 문자는 Shift 또는 대문자 설정을 사용하세요. 단축키는 각 버튼의 안내와 설정을 확인하세요.
- 전체 복사 버튼으로 옮긴 뒤, 받는 문서에서 문자와 부호가 유지되는지 확인하세요. 중요한 내용은 별도 문서에 보관하세요.
