A partition of a number is a way of expressing it as the sum of some number of positive integers. For example, the partitions of 3 are: 3, 2+1, and 1+1+1 (notice how the order of the addends is disregarded). There is no known, simple formula that gives the number of partitions of a number.
A partion of a number is the number of ways to express that integer as a sum of another. For example, the partions of 3 are: 3, {2,1}, and {1,1,1}. There is no simple formula that gives the number of partitions of a number, but many techniques can be found in the article below.
