    • 구구단을 외우다 - memorize one's tables
    • 구구단을 외자 - multiplication table challenge, a game students play to practice the tables. The game starts with a short song. Students take turns testing each other. If you get something wrong, you lose and get a punishment, like a flick on the forehead. "외자" is a shorten form of "외우자" = "Let's memorize".
구구단
2단 3단 …… 9단
2×1=2 3×1=3 …… 9×1=9
2×2=4 3×2=6 …… 9×2=18
…… …… …… ……
2×9=18 3×9=27 …… 9×9=81

Examples

  • 1 + 2 [일 더하기 이]
  • 1 + 2 = 3 [일 더하기 이는 삼]
  • 5 - 4 [오 빼기 사]
  • 3 * 4 [삼 곱하기 사]
  • 5 / 2 (division) [오 나누기 이]
  • 2² [이의 이승 = 이의 제곱] (이에 이승 = 이에 제곱)
  • 2³ [이의 삼승 = 이의 세제곱] (이에 삼승 = 이에 세제곱)

  • ½ [이분의 일] (이분에 일)
  • ¾ [사분의 삼] (사분에 삼)
  • 2.1 [이 점 일]
