![### Problem Statement
Let \( n \) be a positive integer and consider the sum:
\[ S = \sum_{j=1}^{n} \frac{1}{j(j+1)} \]
#### Task
Calculate the actual mathematical value of \( S \) for \( n = 10, 25, 50, \) and \( 100 \). Convince me that you have found the correct answers.
### Explanation
Given the sum in the form
\[ S = \sum_{j=1}^{n} \frac{1}{j(j+1)} \]
we need to find this sum's values for the specified \( n \) values to show detailed steps of our calculations and thus validate the accuracy of our results.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe6e77107-ef1d-4e39-badf-4decafa47f1b%2F7f4220af-1415-4cf8-ac29-f587a0810d59%2Fp99g9ds_processed.png&w=3840&q=75)
