Math question: What is the sum of the digits in the number 4145?

To find the sum of the digits in the number 4145, we first need to identify each digit in the number. The digit in the thousands place is 4, the hundreds place is 1, the tens place is 4, and the units place is 5. Adding these digits together, 4 + 1 + 4 + 5 equals 14. Hence, the sum of the digits in the number 4145 is 14.

Math question: What is the sum of 4145 multiplied by 6, and then divided by 5, subtracted by 1000, divided by 2, and finally squared?

To evaluate this expression, we first multiply 4145 by 6, resulting in 24870. Dividing this by 5 gives us 4974. After subtracting 1000, we obtain 3974. Dividing it by 2 yields 1987. Finally, squaring 1987 gives us 3,948,769. Thus, the answer is 3,948,769.

Math Question: Given the number 4145, what is the sum of the digits if we square it and then divide by the product of its first and last digits?

First, squaring 4145 gives us 17,173,025. The product of the first digit (4) and the last digit (5) is 20. So, dividing 17,173,025 by 20 gives us 858,651.25. To find the sum of the digits of 858,651.25, we add 8 + 5 + 8 + 6 + 5 + 1 + 2 + 5, resulting in 40. Therefore, the sum of the digits of 4145, after squaring and dividing, is 40.
