A slight digression from the main tutorial trail topic to see how the Number accumulates Integers:

All that matters for now is to understand that it is appending Integers (in this case digits) to an ordered list.

Snippets (quotes/extracts)
  [UML-2.5.1] A value of unlimited (“*”) for the insertion point means to insert the new value at the end of the sequence.
  [UML-2.5.1] If isReplaceAll is false and the StructuralFeature is unordered and unique, then adding a value that is already contained in the StructuralFeature has no effect.
  [UML-2.5.1] Adding a value to an ordered StructuralFeature requires an insertion point for the new value given in the insertAt InputPin, which is required for ordered StructuralFeatures when isReplaceAll is false and omitted for unordered StructuralFeatures.
  [UML-2.5.1] If the insertAt InputPin is present, it has type UnlimitedNatural and multiplicity 1..1
