This lesson covers divisibility rules and problem-solving! In the 11th day, 2nd video of the 49-Day TYT Math Camp, we learn the divisibility rules for 6, 12, 15, 18, 20, 24, 30, and 45; then we solve new generation TYT Math questions in the style of ÖSYM (Turkish Higher Education Entrance Examination) step by step. (The last sentence is a repetition of the first paragraph and should be omitted.) 📄 FREE LESSON PDFs: https://www.rehbermatematik.com 📚 49-Day TYT Math Camp Books: 📘 49-Day TYT Math Video Lesson Book – 2027 https://ty.gl/b880d8410 📘 49-Day TYT Math Question Bank – 2027 https://ty.gl/979101eb0 🛒 To purchase online through Kitap İşler: https://www.kitapisler.com/ You can order our books online or purchase them directly at any İŞLER BOOKSTORE throughout Turkey. In this video, we learn how to create new divisibility rules using relatively prime factors. We explain, with examples, which rules must be used together for a number to be divisible by 6, 12, 15, 18, 20, 24, 30, or 45. ⏱️ VIDEO SECTIONS: 00:00 Divisibility Rules – Day 11, Video 2 00:13 Quick Review of Previous Divisibility Rules 00:38 Divisibility by Relatively Prime Factors 01:06 Divisibility Rule by 6 01:16 Divisibility Rule by 12 01:43 Divisibility Rule by 15 01:48 Divisibility Rule by 18 01:55 Divisibility Rule by 24 02:00 Divisibility Rule by 30 02:22 Divisibility Rule by 45 02:36 Question 17 – Divisibility by 6 and the Largest Digit 04:58 Question 18 – Divisibility by 30 and Digit Values 06:03 Question 19 – Remainder from Division by 45 Finding 09:36 Question 20 – Divisibility by 20 (OSYM Style Question) 14:05 Question 21 – Divisibility by 5 and 6 (Mixed Question) 18:32 Question 22 – Divisibility by 3, 4, and 5 (Problem) 22:10 Question 23 – Divisibility by 45 (Receipt Problem) 25:24 Question 24 – Stationery Sales (Grade Question) 32:38 Day 11 Summary and Question Bank Homework What you will learn in this lesson: ✅ Divisibility by relatively prime numbers ✅ Divisibility by 6 ✅ Divisibility by 12 ✅ Divisibility by 15 ✅ Divisibility by 18 ✅ Divisibility by 20 ✅ Divisibility by 24 ✅ Divisibility by 30 ✅ Divisibility by 45 ✅ Remainder from division Finding ✅ Number Problems ✅ Divisibility in Numbers ✅ TYT Mathematics Divisibility Problem Solving ✅ New Generation Divisibility Questions in the Style of ÖSYM (Turkish Higher Education Institutions Examination Center) A natural number that is divisible by each of two relatively prime numbers is also divisible by the product of those numbers. For example, if a number is divisible by both 3 and 4, it is also divisible by 12; if it is divisible by both 5 and 9, it is also divisible by 45. Instead of using all the rules at once in the questions, it makes things easier to start with the rule that depends on the last digit or the last two digits. Then, other conditions such as the sum of the digits are checked. When I say "You First," pause the video and solve the question yourself. Then compare your solution with mine. After completing the video, be sure to solve the assignments for day 11 in the Question Bank. 🔔 Subscribe to the Rehber Matematik channel: https://www.youtube.com/@RehberMatema...
