Math question: What is the sum of the digits in the given number 6541?

To find the sum of the digits, we add the individual digits: 6 + 5 + 4 + 1 = 16. The sum of the digits in the number 6541 is 16.

What is the sum of the first ten natural numbers squared minus the fourth prime number when multiplied by the fifth odd number greater than 1000, divided by the ninth positive even number?

To find the sum of the first ten natural numbers squared, we calculate 1^2 + 2^2 + 3^2 + 4^2 + 5^2 + 6^2 + 7^2 + 8^2 + 9^2 + 10^2 = 385. The fourth prime number is 7, and the fifth odd number greater than 1000 is 1005. So, 385 - 7 multiplied by 1005 equals 385 - 7035 = -6650. The ninth positive even number is 18, hence -6650 divided by 18 equals approximately -369.4. Therefore, the answer is -369.4.

Math question: What is the sum of the digits of the number 6541?

To find the sum of the digits, we add the individual digits together. In 6541, the digits are 6, 5, 4, and 1. Summing these digits, we get 6 + 5 + 4 + 1 = 16. Therefore, the sum of the digits in the number 6541 is 16.
