Math Question: What is the sum of the digits of the number 8811?

To find the sum of the digits, we add each digit individually: 8 + 8 + 1 + 1 = 18.

Math question: If the number 8811 is multiplied by the sum of its digits, what is the result?

To find the sum of the digits in 8811, we add 8 + 8 + 1 + 1 = 18. Multiplying 8811 by 18 gives 158,598. Thus, the result is 158,598 when the number 8811 is multiplied by the sum of its digits.

Math question: How many four-digit numbers can be formed using the digits 8, 8, 1, and 1 (repetition allowed)?

To find the number of possible four-digit numbers, we have to calculate the permutations with repetition. Each digit can be used twice, so the total number of permutations is given by 4! / (2! x 2!) = 6. Hence, there are six different four-digit numbers that can be formed using the digits 8, 8, 1, and 1: 8811, 8118, 8181, 1881, 1818, and 1188.
