Characteristic of a ring

Summary

The characteristic of a ring is the least positive integer nn such that the sum of nn copies of 11 is 00. If there is no such integer, the characteristic is 00. The definition of the characteristic states this precisely.

What this node needs for W2
  • edge instance_of in: at least two examples (0 of 2)
  • edge not_instance_of in: at least one non-example (0 of 1)
  • edge specializes both: the more general notions and the special cases (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.
