Math question for the number 993: What is the sum of the digits when the number 993 is multiplied by its reverse?

To find the reverse of 993, we need to interchange the positions of its digits, which gives us 399. Now, let's multiply 993 by 399. 9 9 3 x 3 9 9 --------- 2 9 7 0 7 3 9 7 0 7 0 + 2 9 7 0 7 0 0 ------------------ 3 9 6 0 1 0 7 Now, we calculate the sum of the digits - 3 + 9 + 6 + 0 + 1 + 0 + 7 = 26. Hence, the answer is 26.

Math Question: What is the sum of the digits in the number 993 after multiplying it by 7 and subtracting 5?

To find the answer, we first multiply 993 by 7, obtaining 6951. Then, by subtracting 5, we get 6946. To find the sum of its digits, we need to split the number into its individual digits: 6, 9, 4, and 6. Adding these digits together gives us 25. Therefore, the sum of the digits in the number 993 after multiplying by 7 and subtracting 5 is 25.

Math Question: What is the sum of the digits of 993 multiplied by the product of the digits of 993, divided by the difference between the largest and smallest digits of 993, squared?

To find the sum of the digits, we add 9 + 9 + 3 = 21. Next, the product of the digits is 9 * 9 * 3 = 243. The largest digit is 9, and the smallest digit is 3, so their difference is 9 - 3 = 6. The square of 6 is 36. Therefore, the final result is (21 * 243) / 36 = 142.25.
