What is the sum of the digits of the number 3690?

The sum of the digits of 3690 is 3 + 6 + 9 + 0 = 18.

What is the sum of the digits of 3690 plus twice its tens digit, minus its units digit, divided by its hundreds digit, multiplied by 10, subtracted by the product of its thousands digit and its tens digit?

To solve this, first find the digits of 3690: thousands digit (3), hundreds digit (6), tens digit (9), and units digit (0). The sum of the digits is 3 + 6 + 9 + 0 = 18. Twice the tens digit is 2 * 9 = 18. Subtracting the units digit gives 18 - 0 = 18. Divide this by the hundreds digit: 18 ÷ 6 = 3. Multiplying by 10, we get 3 * 10 = 30. Finally, subtract the product of the thousands digit (3) and the tens digit (9): 30 - (3 * 9) = 30 - 27 = 3. Therefore, the answer is 3.

Math question: What is the sum of all the even numbers from 2 to 3690, inclusive?

To find the sum, first, identify the number of terms in the series. Dividing 3690 by 2 gives us 1845, which represents the number of terms. Using the formula for the sum of an arithmetic series, S = (n/2)(a + l), where n is the number of terms, a is the first term, and l is the last term, we can calculate. The first term is 2, and the last term can be found by multiplying the number of terms by 2, which gives us 3690. Plugging these values into the formula, we get S = (1845/2)(2 + 3690) = 1845 * 3692 = 6,814,340. Therefore, the sum of all the even numbers from 2 to 3690 is 6,814,340.
