Simple Roman Numerals (all examples are in C major)

I - Tonic. (C Major)
II - Supertonic (D Minor)
III - Mediant (E Minor)
IV - Sub Dominant (F Major)
V - Dominant (G Major)
VI - Sub-mediant (A Minor)
VII - Sub-tonic (B-Diminished)

The triad is made up of a root, third and fifth. The Root always stays the same. The fifth and third move accordingly

Triads come in different versions, according to which note is in the base

a - root - CEG
b - 1st inversion - EGC
c - 2nd inversion - GEC
d - 3rd inversion (in a dominant 7th where the 7th is flattened,) Bb-C-E-G

a flat or sharp sign before the chord indicates that the root of the chord is sharpened/flattened accordingly
i.e
bIIb - first inversion of the flattened supertonic
F - Ab - Db (the root is Db) known as the now-infamous n6th!
