SUMMARY
The mathematical puzzle of distributing 20 lbs of pressure across 5 hours using only odd numbers reveals that a solution is impossible if zero is excluded. The discussion confirms that two odd numbers always sum to an even number, making it impossible to achieve an odd total of 20 lbs with five odd integers. However, if zero is permitted as a value, a potential solution exists: 17 lbs in the first hour, followed by 1 lb in the next three hours, and 0 lbs in the last hour. Ultimately, the consensus is that without zero, the problem has no valid solutions.
