Question: How many prime numbers are there between 1269 and its square root, inclusively?

To find the prime numbers between 1269 and its square root (35.64), we can check if each number in this range is divisible by any numbers less than or equal to its square root. Starting from 1270, we find that it is divisible by 2, so it is not a prime number. Similarly, 1271, 1272, and 1273 are not prime as they are divisible by 17, 2, and 13 respectively. However, 1274 is divisible by 2 and 7, making it not prime. Continuing this process, we find that 1275, 1276, 1277, 1278, 1279, and 1280 are also not prime numbers as they have divisors. Finally, we reach 1281 where we can see it is not divisible by any numbers up to its square root, indicating that it is a prime number. Therefore, between 1269 and its square root, there is only one prime number, which is 1281.

Math question: What is the sum of the digits of the number 1269?

To find the sum of the digits of 1269, we add the individual digits together. The digit 1 + 2 + 6 + 9 equals 18. Therefore, the sum of the digits of the number 1269 is 18.

Math question: If you take the number 1269 and add 202 to it, multiply the result by 3, and then subtract 300, what is the final answer?

To solve this, we start with 1269 and add 202, resulting in 1471. Multiplying this by 3, we get 4413. Subtracting 300 from it gives us the final answer of 4113.
