Math Question: What is the sum of the digits in the number 1825?

To find the sum of the digits in 1825, we need to add the individual digits together. Starting from the left, the digits in 1825 are 1, 8, 2, and 5. Adding them up, we have: 1 + 8 + 2 + 5 = 16. Therefore, the sum of the digits in the number 1825 is 16.

Math Question: If the number 1825 is increased by twice the square of its tens digit minus the product of its units and hundreds digits, what is the resulting number?

To solve this problem, we first determine the tens digit, which is 8 in 1825. Taking twice the square of 8 gives us 2 * 8^2 = 128. The units digit is 5 and the hundreds digit is 2, so the product of the units and hundreds digits is 5 * 2 = 10. Subtracting the product from twice the square gives us 128 - 10 = 118. Hence, the resulting number is 118 + 1825 = 1943.

Math question: What is the sum of the digits in the number 1825?

To find the sum of the digits in 1825, we add the individual digits together. The digit 1 represents 1000, 8 represents 800, 2 represents 20, and 5 represents 5. So, the sum of these digits is 1000 + 800 + 20 + 5, which equals 1825.
