Math question: What is the sum of the digits in the number 3121?

To find the sum of the digits in the number 3121, we can break it down into its individual digits: 3, 1, 2, and 1. Adding these digits together gives us 3 + 1 + 2 + 1 = 7. Hence, the sum of the digits in the number 3121 is 7.

Math question: If the number 3121 is multiplied by 3 and then divided by the square root of 9, what is the result?

To solve this, let's break it down step by step. First, multiply 3121 by 3, which gives us 9363. Then, we need to find the square root of 9, which is 3. Now, divide 9363 by 3, and we get 3121 again. Therefore, the result is 3121. The entire process confirms that multiplying a number by 3 and dividing it by the square root of 9 will give the original number back, irrespective of its value. This property holds true for all numbers.

Math question: What is the sum of the digits of the number 3121?

To find the sum of the digits of 3121, we add the individual digits together. The digit 3 + 1 + 2 + 1 equals 7. Therefore, the sum of the digits of 3121 is 7.
