Math question: If you subtract a number from 312 and divide the difference by 3, then add 42 to the quotient, what is the result?

To find the result, we first subtract the number from 312, which gives us the difference. Then, we divide the difference by 3. Adding 42 to the quotient will yield the final answer. Let the number be x. Thus, the result is (312-x)/3 + 42.

Math question: What is the sum of the even integers greater than 100 and less than 400?

To find the sum, we need to determine all the even numbers between 100 and 400. The first even number within this range is 102, and the last even number is 398. We observe that the difference between consecutive even numbers is 2. So, the sum of the even integers can be calculated by using the formula for the sum of an arithmetic series: Sum = (n/2)(first term + last term) = (n/2)(102 + 398) Now, we need to find the number of terms in this series. To do that, we calculate the number of terms by subtracting the first term from the last term, adding 2, and then dividing by 2: Number of terms = (last term - first term)/2 + 1 = (398 - 102)/2 + 1 Evaluating this expression, we have: Number of terms = 297/2 + 1 = 149 + 1 = 150 Now, substituting the values into the formula: Sum = (150/2)(102 + 398) = 75 × 500 = 37,500 Therefore, the sum of the even integers between 100 and 400 is 37,500.

Math Question: What is the sum of the digits of the number 312?

To find the sum of the digits of 312, we separate the number into its constituent digits; 3, 1, and 2. Then we add them together: 3 + 1 + 2 = 6. Hence, the sum of the digits of the number 312 is 6. A number's digit sum is obtained by adding up all its individual digits. It is a useful concept in various mathematical operations like divisibility rules, digital roots, and even in cryptography.
