Math Question: What is the sum of the first 10 positive odd numbers greater than 2661?

To find the sum of the first 10 positive odd numbers greater than 2661, we first determine the first odd number after 2661, which is 2663. The next odd numbers are obtained by increasing this value by 2 successively: 2665, 2667, 2669, 2671, 2673, 2675, 2677, 2679, and 2681. Adding all these numbers together, the sum is 26,736.

Math Question: What is the remainder when 2661 is divided by 9?

To find the remainder, we sum the digits of 2661: 2 + 6 + 6 + 1 = 15. Since 15 is not divisible by 9, the remainder is 15.

Math question: What is the remainder when the number 2661 is divided by 9?

To find the remainder when 2661 is divided by 9, we can add up its digits: 2 + 6 + 6 + 1 = 15. Since 15 is still greater than 9, we continue adding: 1 + 5 = 6. Hence, 6 is the remainder when 2661 is divided by 9.
