# Augend vs. Addend: What's the Difference?

By Harlon Moss & Aimie Carlson || Updated on May 23, 2024

**An augend is the initial number to which another number (addend) is added in a mathematical addition operation.**

## Key Differences

An augend is the first number in an addition operation. It is the initial value to which another number is added. In the equation 5 + 3, the number 5 is the augend. The augend sets the base for the addition process and determines the starting point for the calculation. An addend, on the other hand, is any number that is added to the augend. In the same equation 5 + 3, the number 3 is the addend. The addend contributes to the total sum when combined with the augend.

In terms of their roles, the augend remains static as the initial number, while addends can vary and be multiple. For instance, in 7 + 2 + 4, 7 is the augend, and 2 and 4 are addends. The sum results from adding all addends to the augend.

The distinction between augend and addend helps in understanding the structure of addition operations. The augend's role is foundational, whereas addends augment the initial value. This distinction is crucial in arithmetic and algebra to clearly define the components of an addition equation.
