Tal skrevet opdelt

At skrive tal opdelt betyder, at vi skriver et tal som en sum af værdien af hvert ciffer.
Vi kan bruge et skema med pladsværdier til at finde værdien af hvert ciffer.

Eksempel

Lad os skrive start color #11accd, 3, end color #11accd, comma, start color #7854ab, 4, end color #7854ab, start color #1fab54, 0, end color #1fab54, start color #ca337c, 5, end color #ca337c opdelt.
