Math question: Find the remainder when 218 is divided by the sum of its digits multiplied by their difference plus the square root of its tens digit minus the units digit.

To find the remainder when 218 is divided, we start by calculating the sum of its digits: 2 + 1 + 8 = 11. Next, we find the difference between its digits: 2 - 8 = -6. The square root of the tens digit (1) is 1. Taking all these calculations, we have 11 * (-6) + sqrt(1) - 8 = -65. Finally, we divide 218 by -65 to get the remainder. However, since dividing by a negative number may not yield a meaningful remainder, we can say that the remainder is -65.

Math question: What is the least positive integer that is divisible by both 218 and 3?

To find the least common multiple (LCM) of two numbers, we need to first determine their prime factorizations. The prime factorization of 218 is 2 * 109, while the prime factorization of 3 is 3. To find the LCM, we need to take the highest power of each prime factor that appears in either of the two numbers. Thus, the LCM will be 2 * 109 * 3 = 654. Therefore, the least positive integer divisible by both 218 and 3 is 654.

Math question: If 218 is divided by a certain number and multiplied by half of itself, what is the result?

To solve this problem, let's assume the unknown number is represented by 'x'. We can express the given statement as: (218 ÷ x) × (218 ÷ 2). By simplifying the expression, we obtain (109x) ÷ 2 or (54.5x). So, the result of the given operation is equal to 54.5 times the unknown number 'x'.
