The evaluation of a situation or problem, including review from various aspects or points of view. In computing, analysis commonly involves such features as flow control, error control, and evaluation of efficiency. Often the overall problem is divided into smaller components that can be more easily dealt with. See also flow analysis, numerical analysis, systems analysis. Compare synthesis.

Branch of mathematics concerned with limiting processes on axiomatic number systems; calculus of variations and infinitesimal calculus is now called analysis.

In chemistry, the determination of the composition of substances; see analytical chemistry.
