Question: How many different ways can the number 1108 be written as the sum of two prime numbers?

To find the number of ways, we need to check all possible pairs of prime numbers that sum up to 1108. Let's begin by listing out the prime numbers less than or equal to 1108: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, 211, 223, 227, 229, 233, 239, 241, 251, 257, 263, 269, 271, 277, 281, 283, 293, 307, 311, 313, 317, 331, 337, 347, 349, 353, 359, 367, 373, 379, 383, 389, 397, 401, 409, 419, 421, 431, 433, 439, 443, 449, 457, 461, 463, 467, 479, 487, 491, 499, 503, 509, 521, 523, 541, 547, 557, 563, 569, 571, 577, 587, 593, 599, 601, 607, 613, 617, 619, 631, 641, 643, 647, 653, 659, 661, 673, 677, 683, 691, 701, 709, 719, 727, 733, 739, 743, 751, 757, 761, 769, 773, 787, 797, 809, 811, 821, 823, 827, 829, 839, 853, 857, 859, 863, 877, 881, 883, 887, 907, 911, 919, 929, 937, 941, 947, 953, 967, 971, 977, 983, 991, 997. Now, we can systematically go through all the pairs and check if their sum equals 1108. It turns out that there is only one way to write 1108 as the sum of two prime numbers, which is 1108 = 7 + 1101. Thus, the number 1108 can be written as the sum of two prime numbers in only one way: 1108 = 7 + 1101.

Math question: What is the smallest positive integer greater than 1108 that is divisible by both 7 and 8?

To find the smallest common multiple, we need to find the least common multiple (LCM) of 7 and 8. Prime factorizing 7 gives us 7 = 7^1, and for 8, we have 8 = 2^3. To compute the LCM, we need to consider the highest power for each prime factor. Since the highest power of 2 is 3 and the highest power of 7 is 1, we multiply 2^3 and 7^1 to get the LCM. LCM(7, 8) = 2^3 × 7^1 = 56. Therefore, the smallest positive integer greater than 1108 that is divisible by both 7 and 8 is 56.

Math Question: If you subtract the product of 6 squared and 3 from the sum of 1108 and 43 multiplied by 5, what is the result?

To find the result, we start by calculating the product of 6 squared, which is 6^2 = 36. Then, we multiply 43 by 5, resulting in 43 * 5 = 215. Next, we sum 1108 with 215 to obtain 1108 + 215 = 1323. Finally, we subtract 36 from 1323, giving us 1323 - 36 = 1287. Therefore, the result is 1287.
