Math question: If a number is increased by 32 and then multiplied by 4, what is the resulting value?

To find the resulting value, first, we increase the number by 32: 812 + 32 = 844. Next, we multiply this sum by 4: 844 * 4 = 3376. Therefore, the resulting value when the given number 812 is increased by 32 and then multiplied by 4 is 3376.

What is the sum of the three prime factors of the number 812?

To find the prime factors of 812, we divide it by prime numbers starting from 2. 812 ÷ 2 = 406, which is also divisible by 2, giving 203. Since 203 is not divisible by 2, we try the next prime number, 3. 203 ÷ 3 = 67. 67 is a prime number itself, so we have found all the prime factors of 812: 2, 2, and 67. Adding these prime factors together, we get 2 + 2 + 67 = 71.

Math Question: Find the sum of all the digits in the number 812.

To find the sum of all the digits in 812, we need to break it down into its individual digits. The number 812 can be written as 8 * 100 + 1 * 10 + 2. Therefore, the sum of the digits is 8 + 1 + 2 = 11.
