Math question: If the number 1240 is divided by 4, added to 50, multiplied by 2, and then subtracted by 200, what is the final result?

To find the final result, let's break down the operations step by step. Firstly, 1240 divided by 4 equals 310. Adding 50 to 310 gives 360. Multiplying 360 by 2 yields 720. Finally, subtracting 200 from 720 results in 520. Therefore, the final result is 520.

Math Question: What is the sum of the prime factors of 1240, excluding 1?

To find the prime factors of 1240, we start by dividing it successively by prime numbers. Dividing 1240 by 2 gives us 620. Continuing this process, we find that the prime factorization of 1240 is 2^3 * 5 * 31. The sum of these prime factors (excluding 1) is 2 + 2 + 2 + 5 + 31 = 42. Therefore, the sum of the prime factors of 1240, excluding 1, is 42.

Math question: If a number is divided by 5, multiplied by 8, and then divided by 2, what is the result when 1240 is subjected to this operation?

For the number 1240, dividing it by 5 gives us 248. Multiplying by 8 yields 1984. Finally, dividing by 2 results in 992. Therefore, the final answer after subjecting the number 1240 to this operation is 992.
