Math question: If the number 985 is divided by 5 and then multiplied by 4, what is the result?

To find the result, we divide 985 by 5: 985 ÷ 5 = 197. Then we multiply 197 by 4: 197 x 4 = 788. Therefore, the result is 788.

Math question: What is the sum of the digits of the number obtained by cubing 985 and then subtracting 985? (up to 200 characters)

To find the sum of the digits of the number obtained by cubing 985 and subtracting 985, we start by calculating: 985^3 - 985 = 937'756'040 - 985 = 937'755'055. The sum of the digits 9 + 3 + 7 + 7 + 5 + 5 + 0 + 5 + 5 = 46. Hence, the sum of the digits is 46. (up to 500 characters)

Math question: What is the smallest prime number greater than 985 that is also a multiple of 5?

The smallest prime number greater than 985 is 991. To verify if it is a multiple of 5, we perform the division 991 ÷ 5. Since the result is 198 with no remainder, 991 is a multiple of 5. Therefore, the smallest prime number greater than 985 that is also a multiple of 5 is 991.
