The Associative Laws say that it doesn't matter how we group the numbers (i.e. which we calculate first) ... ... when we add : (a + b) + c = a + (b + c). ... or when we multiply : (a Ã b) Ã c = a Ã (b Ã c).

Generally, after pushing the button on the PCA, initial relief of discomfort can begin in as little as five minutes. The PCA medication kicks in quickly, but usually lasts for only a few hours â a much shorter time period than oral pain pills. Oral pain pills dissolve in the stomach and take between 30-45 minutes to start working from the time they are swallowed. Because these pills dissolve slowly in the stomach, they generally work to control pain for 3-4 hours at a time.
