translation: Ta biết rằng ta có thể hiểu nó là 23 chia cho 6. Và nếu ta thực sự chia 23 cho 6-- hãy thực hiện nào. Vậy ta chia 23 cho 6.
translation: Well, we already know that 18/6 is the same thing as 18 divided by 6, or 3. So this is the same thing as 3. So we know that 23 over 6, which is the same thing as 18 plus 5 over 6, is the same thing as 3 plus 5/6.
