What is the sum of the digits of the number 6521? Express your answer as a whole number.

To find the sum of the digits, we add them together. The digit in the thousands place is 6, the digit in the hundreds place is 5, the digit in the tens place is 2, and the digit in the ones place is 1. Adding these digits gives us 6 + 5 + 2 + 1 = 14. Therefore, the sum of the digits of the number 6521 is 14.

Math question: What is the sum of the thousands digit, the double of the hundreds digit, and the square root of the tens digit minus the units digit of the number 6521?

To evaluate the sum, we break down the number 6521. The thousands digit is 6, the hundreds digit is 5, the tens digit is 2, and the units digit is 1. The double of the hundreds digit is 5 * 2 = 10. The square root of the tens digit is √2 ≈ 1.41421. Thus, the sum is 6 + 10 + 1.41421 - 1, which equals approximately 16.41421.

What is the sum of the ones, tens, hundreds, and thousands digit of the number 6521?

To find the sum, we add the digit values individually: 6 + 5 + 2 + 1 = 14. Therefore, the sum of the ones, tens, hundreds, and thousands digit of the number 6521 is 14. This calculation helps to understand the contribution of each digit to the overall numerical value and reinforces base-10 place value concepts.
