🧮주산 100일 챌린지 16일차 - 기초 2편🇰🇷 안녕하세요. 기초2편이예요. 😃주산을 몰라도, 3가지만 알면 더하기 빼기가 가능하도록 영상을 만들어봤어요. (물론 연습은 필요하지만!) 😁오늘은 5의 대한 보충수(짝꿍수)개념을 익혀볼께요. 5를 만들기 위해 필요한 수가 보충수 입니다. 예)2가 있어요. 5가 되려면 얼마가 필요하죠? 3이죠 2의 보충수는 3! 하지만 10의 보충수도 있기 때문에 5의 보충수는 짝꿍수라고 일컬을께요. 😃오늘도 1분영상 보시고, 머리 좋아지셔요. >< 다음 3편으로 찾아올께요! -> 커뮤니티에서 만나요! 🧮Day 16 of the Abacus 100-day Challenge - Basic 2 🇰🇷 Hello. It's the second installment of the basics. Even if you don't know abacus, you can add and subtract if you know three things. I made a video. (Of course, practice is necessary!) 😁 today, we will learn the concept of complementary numbers (buddy numbers) for 5. The number needed to make 5 is a supplement. Yes, there is 2. How much is needed to make it 5? It's 3. The complement for 2 is 3! However, there are also 10 complement, so... The complement of 5 will be called "buddy numbers" 😃 watch the 1-minute video today, You're getting smarter. >< I'll come back with the next episode! #주산 #암산 #머리가좋아지는법 #수학 #유아수학 #연산 #유아 #엄마표수학 #Soroban #そろばん #Abacum #MentalArithmetic #HowtoGetSmarter #Mathematics #EarlyMathematics #Arithmetic
