Math question: What is the sum of all positive integers less than or equal to 656?

To find the sum of a series of consecutive numbers, we can use the formula for the sum of an arithmetic series: sum = (n/2)(first term + last term), where n is the number of terms. In this case, the first term is 1 and the last term is 656. We need to find the number of terms. The formula to find the number of terms in an arithmetic series is: n = (last term - first term + common difference)/common difference. Here, the common difference is 1. Plug in the values: n = (656 - 1 + 1)/1 = 656. Now we can find the sum: sum = (656/2)(1 + 656) = 328(657) = 215,496. Therefore, the sum of all positive integers less than or equal to 656 is 215,496.

Math question: What is the sum of the first 10 odd numbers greater than 656?

To find the sum of the first 10 odd numbers greater than 656, we can use the formula for the sum of an arithmetic series. The first odd number greater than 656 is 657, and the common difference between consecutive odd numbers is 2. So, the arithmetic series can be written as 657, 659, 661, ..., 673. The nth term can be found using the formula nth term = first term + (n - 1) * common difference. Plugging in the values, the tenth term is 657 + (10 - 1) * 2 = 675. Now, using the formula for the sum of an arithmetic series, sum = (n / 2) * (first term + last term). Substituting the values, sum = (10 / 2) * (657 + 675) = 5 * 1332 = 6660. Therefore, the sum of the first 10 odd numbers greater than 656 is 6660.

What is the sum of double the number 656, triple the square of 656, and half of the cube root of 656?

The sum can be calculated as (2 * 656) + (3 * (656^2)) + (1/2 * ∛656). Simplifying this expression gives us 1312 + 1281496 + 15.55 ≈ 1282823.55. Thus, the sum is approximately 1,282,823.55.
