The Aggregate is a term used to describe the combination of multiple elements into one. It is often used in mathematics and economics to refer to the sum of all parts, such as the total of a group of numbers or the total of a set of data. In other contexts, it can refer to the combination of different elements into a single entity, such as a group of people or a collection of objects. The Aggregate is also used to describe the collective whole of a group or organization, such as the total number of employees in a company or the total amount of money in a bank account.
