- Cofactor (linear algebra) The signed minor of a matrix
- Minor (linear algebra) as an alternative name for the determinant of a smaller matrix than that which it describes
- Cofactor (biochemistry) is a substance that needs to be present in addition to an enzyme for a certain reaction to take place.
- Shannon cofactor is a derived function of another function, a notion useful in computer science and mathematics.
- Cofactor (epidemiology) is a condition that exacerbates the effects of another condition; for instance, while chlamydia infection on its own will not cause cervical cancer, it increases the risk that HPV infection will do so.
In linear algebra, the cofactor describes a particular construction that is useful for calculating both the determinant and inverse of square matrices. Specifically the cofactor of an entry of a matrix is the signed minor of that entry.

In algebra, a determinant is a function depending on n that associates a scalar, det(A), to every n×n square matrix A. The fundamental geometric meaning of a determinant is as the scale factor for volume when A

Enzymes are proteins that catalyze (i.e. accelerate) chemical reactions.[1] In enzymatic reactions, the molecules at the beginning of the process are called substrates, and the enzyme converts them into different molecules, the products.
