Math question: Is 3813 divisible by 11?

To determine if 3813 is divisible by 11, we can use the divisibility rule for 11. We sum the alternating digits from right to left. In this case, 3+3 (8 is skipped) + 1-3 = 4. Since 4 is not divisible by 11, neither is 3813. Therefore, 3813 is not divisible by 11.

Math question: What is the sum of the digits in the number 3813?

To find the sum of the digits in 3813, we add each digit together: 3 + 8 + 1 + 3 = 15. Therefore, the sum of the digits in 3813 is 15.

What is the sum of all the digits in the number 3813?

To find the sum, we add the individual digits: 3 + 8 + 1 + 3 = 15. Therefore, the sum of all the digits in the number 3813 is 15.
