Relating to or involving the process of calculation; connected with mathematical computation or problem-solving.
From calculation (noun) plus the suffix -al, which turns nouns into adjectives. Calculation comes from Latin calculatio, derived from calculare.
In physics and mathematics, 'calculational' is the preferred adjective when discussing computational methods—it's more specific than 'mathematical' because it emphasizes the actual process of computing rather than math concepts in general.
