Math question: What is the sum of the individual digits of the number 7814?

To find the sum of the digits in 7814, we can break it down into its individual digits; 7 + 8 + 1 + 4 = 20. Hence, the sum of the digits in the number 7814 is 20.

What is the sum of the digits in the number 7814?

To find the sum of the digits, we add 7 + 8 + 1 + 4 which equals 20.

Question: What is the sum of the digits of the number 7814 when each digit is squared, multiplied by the next digit, and then added together?

To solve this, we start by squaring each digit: 7^2 = 49, 8^2 = 64, 1^2 = 1, and 4^2 = 16. Next, we multiply each squared digit by the next digit: 49 * 8 = 392, 64 * 1 = 64, and 1 * 4 = 4. Finally, we add up the products to get the result: 392 + 64 + 4 = 460. Thus, the sum of the digits of the number 7814 when squared, multiplied, and added is 460.
