The term 'evaluate' in the realm of mathematics pertains to the computation of the numeric worth of a specified expression. It comprises the execution of operations like addition, subtraction, multiplication, division, and so on, in the proper sequence. Typically, this follows the BIDMAS/BODMAS principle, which stands for Brackets, Indices/Orders, Division/Multiplication, Addition/Subtraction.
