The term 'combined' is most closely related to which mathematical operation?

The term 'combined' is most closely related to addition because it refers to the process of putting together quantities to find a total. In mathematics, when two or more numbers are combined, they are generally added together to form a new number that represents their total. This concept aligns with how addition is used to aggregate values, making it the most fitting operation associated with the term 'combined.'

In contrast, subtraction would imply taking something away, division involves splitting into parts, and multiplication could be seen as repeated addition but does not directly align with the notion of simply combining numbers to find their sum.
