What is stream order and how would I identify the stream order of a specific tributary by looking at a drainage basin ?

I'm trying to complete a revision assignment on drainage basins and I can't seem to find the information I need anywhere.

Strahler's (1952) stream order system is a simple method of classifying stream segments based on the number of tributaries upstream. A stream with no tributaries (headwater stream) is considered a first order stream. A segment downstream of the confluence of two first order streams is a second order stream. Thus, a nth order stream is always located downstream of the confluence of two (n-1)th order streams.
