IPA: /ˈɔːɡɛnd/
KK: /ˈɔːɡɛnd/
A number that is added to another number in an addition operation.
In the equation 5 + 3, the number 5 is the augend.
Augend is derived from the Latin word 'augere' (meaning to increase) and the suffix '-end' (indicating something that is acted upon). The term refers to a number that is to be added to another number in an addition operation, thus it is the number that increases the total.
Think of 'augere' meaning to increase, and remember that an 'augend' is the number that increases another in addition.
