Math Question: What is the smallest positive number that, when divided by 3, leaves a remainder of 1, when divided by 5 leaves a remainder of 3, and when divided by 7 leaves a remainder of 5?

Let's solve this problem through the Chinese Remainder Theorem. We need to find a number that leaves a remainder of 1 when divided by 3. To satisfy this condition, the number can be represented as 3k + 1, where k is an integer. Similarly, the number must leave a remainder of 3 when divided by 5, which can be represented as 5m + 3. Additionally, the number must leave a remainder of 5 when divided by 7, which can be represented as 7n + 5. Using the Chinese Remainder Theorem, we can combine these equations into one equation 3k + 1 = 5m + 3 = 7n + 5. Solving this system of congruences, we find that the smallest positive number satisfying these conditions is 113.

Math Question: What is the largest prime number between 111 and 200?

To find the largest prime number between 111 and 200, we examine each number within the range. Starting with 112, we can see that it is divisible by 2. Moving on, 113 is a prime as it has no divisors other than 1 and itself. Then, when checking 114, we find it divisible by 2 again. Continuing this process, 115 is divisible by 5, 116 by 2, 117 by 3, 118 by 2, 119 by 7, 120 is divisible by 2 and 3, and 121 is divisible by 11. Moving forward, 122 is divisible by 2, 123 by 3, 124 by 2, 125 by 5, 126 by 2 and 3, and so on. Listing all the numbers in this way, we observe that numbers 187, 189, 191, 193, 197, and 199 do not have any divisors other than 1 and themselves, making them prime. Therefore, the largest prime number between 111 and 200 is 199.

Math question: What is the sum of the first ten prime numbers greater than 100?

To find the sum of the first ten prime numbers greater than 100, we start by listing out the prime numbers greater than 100, which are 101, 103, 107, 109, 113, 127, 131, 137, 139, and 149. Adding these ten numbers, we get 111 + 103 + 107 + 109 + 113 + 127 + 131 + 137 + 139 + 149 = 1195. Therefore, the sum of the first ten prime numbers greater than 100 is 1195.
