Math question: What is the sum of all digits in the number 1812?

To calculate the sum of all digits in the number 1812, we add each digit together: 1 + 8 + 1 + 2 = 12. Thus, the sum of all digits in 1812 is 12.

Math question: If 1812 is equal to x, what is the value of (3x + 6) ÷ (2x - 3)?

To find the value, substitute 1812 in place of x: (3 * 1812 + 6) ÷ (2 * 1812 - 3). Simplifying, we get (5436 + 6) ÷ (3624 - 3). Further simplifying, (5442) ÷ (3621). Using long division, we find the quotient is 1.5029 (rounded to 4 decimal places). Thus, the value of (3x + 6) ÷ (2x - 3) when x = 1812 is approximately 1.5029.

Math question: Find the remainder when 1812 is divided by 23, then subtract 60% of the sum of its digits, and multiply the result by the square root of the product of its digits.

To find the remainder when 1812 is divided by 23, we perform long division: 23 goes into 181 (7 times) which results in 161; subtracting 161 from 181 gives a remainder of 20. The sum of the digits of 1812 is 1 + 8 + 1 + 2 = 12. 60% of 12 is 7.2. Subtracting 7.2 from 20, we obtain 12.8. The product of the digits of 1812 is 1 × 8 × 1 × 2 = 16. Taking the square root gives √16 = 4. Multiplying 12.8 by 4, we get 51.2 as the final result.
