The idea
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.
In practice
A distance on a trail sign, written decimal or binary, differs in base and agrees in method.
Where people slip
One scheme, every base — learn it once.
