Welcome to the AoPSWiki! The AoPSWiki is a wiki (or an publicly editable online resource) project administered by the [[Art of Problem Solving]] for supporting educational content useful to students of [[mathematics]], [[science]], [[computer science]], [[technology]], and other problem solving topics. Unlike most online resources, the AoPSWiki is meant to be easily readable by even the least advanced student. Also, the AoPSWiki, being a wiki, can be edited by anyone!

During AMC testing week, the AoPS Wiki is in read-only mode. No edits can be made.

Problem of the Week

1983 AIME, Problem 13

For $\{1, 2, 3, \ldots, n\}$ and each of its non-empty subsets a unique alternating sum is defined as follows. Arrange the numbers in the subset in decreasing order and then, beginning with the largest, alternately add and subtract successive numbers. For example, the alternating sum for $\{1, 2, 3, 6,9\}$ is $9-6+3-2+1=5$ and for $\{5\}$ it is simply $5$. Find the sum of all such alternating sums for $n=7$.
