I apologize for the confusion. Let's break it down step by step:
1. The first pipe section does not need a fitting at one end.
2. Each subsequent pipe section requires a fitting at each end to connect it to the adjacent sections.
3. For 13 pipe sections, we need fittings at both ends for sections 2 through 13.
4. So, for 13 pipe sections, we need:
1 fitting for the first end of the first section
2 fittings for each end of sections 2 through 13
1 fitting for the last end of the last section
Adding these up:
1 + (2 * 12) + 1 = 25 fittings
Therefore, 25 fittings are needed to install plumbing with 13 pipe sections.
