Definition: In mathematics, a "pentimento" is an operation that involves dividing by 5. This can be seen as a special case of modular arithmetic where division by 5 is allowed.
For example:
- The division of 10 by 5 results in 2.
- The division of 15 by 5 results in 3, since 5
3 = 15.
- The division of 20 by 5 results in 4, because 5
closed bracket.
