Math question: What is the sum of all the even numbers from 2 to 3940?

To find the sum of all even numbers from 2 to 3940, we can use the formula for the sum of an arithmetic series. The first term is 2, the last term is 3940, and the common difference is 2 since we are summing even numbers. The formula for the sum of an arithmetic series is S = (n/2)(a + l), where S is the sum, n is the number of terms, a is the first term, and l is the last term. The number of terms can be calculated as (3940 - 2) / 2 + 1 = 1969. Plugging these values into the formula, we get S = (1969/2)(2 + 3940) = 1969 * 1970 = 3,872,130. Therefore, the sum of all the even numbers from 2 to 3940 is 3,872,130.

Math question: What is the sum of the digits of the number 3940?

To find the sum of the digits, we add each individual digit together. In the number 3940, the digit 3 represents three thousand, 9 represents nine hundred, 4 represents four tens, and 0 represents zero units. Adding these digits together, we get 3 + 9 + 4 + 0 = 16. Therefore, the sum of the digits of 3940 is 16.

Math question: If 3940 is multiplied by the sum of its digits, what is the result?

To find the sum of the digits, we add 3 + 9 + 4 + 0 = 16. Now, multiplying 3940 by 16, we get 63,040 as the result.
