: Historically, reduction was defined as the loss of oxygen from a compound.

: Used in calculus to solve complex integrals by breaking them down into simpler steps, often expressed as a recursive relationship.

: In organic and biological systems, reduction often involves adding hydrogen atoms to a molecule. 2. Mathematics: Simplifying Expressions

In chemistry, reduction is one half of a . It is defined as:

: Because electrons are negatively charged, gaining them reduces the overall charge or oxidation number of the substance.

: An atom or molecule acquires one or more electrons.

In math, reduction refers to the process of rewriting a complex expression into a simpler, more manageable form.
