Positional Notation
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Decimal and binary run the same positional scheme with different bases: each digit multiplies the base raised to its position, summed right to left from position zero.
Show
A distance on a trail sign, written decimal or binary, differs in base and agrees in method.
Watch for
One scheme, every base — learn it once.
