The associative property of addition states that the way in which numbers are grouped when adding does not change the sum. For example, when adding three numbers, (a + b) + c is the same as a + (b + c). This property emphasizes that the focus can be on the numbers being added rather than their arrangement, providing flexibility in calculation.
Addens is a family-name, mostly concentrated in the North of Germany and the Netherlands.
