Math question: What is the sum of the digits of the number 7817?

To find the sum of the digits of the number 7817, we add 7 + 8 + 1 + 7, which equals 23.

Math Question: What is the sum of the digits in the number 7817, multiplied by the product of its digits, divided by the difference between the maximum and minimum digits in the number?

To find the sum of digits in 7817, we add 7+8+1+7 which equals 23. The product of its digits is 7*8*1*7=392. The maximum digit is 8 and the minimum digit is 1, so the difference is 8-1=7. Therefore, the final calculation is (23*392)/7=1288. Thus, the result is 1288.

Math question: If you add 791 to a number and then subtract 74, the result is 7817. What is the number?

To find the number, let's reverse the operations. First, subtract 7817 from 791, giving us -7026. Then, reverse the subtraction by adding 74 to -7026, resulting in -6952. Thus, the number is -6952.
