The Precambrian is infact divided into 3 - the Hadean(4500-3950 Ma), Archaean (3950-2500 Ma), and Proterozoic (2500-542 Ma) Eons.

Ma = Mega-annum and means 1 million years. So 4500 Ma = 4500 million years old.

The Archean and Proterozoic Eons are in turn subdivided into Eras as follows:

Archean:

3950 Ma

Eoarchean

3600 Ma

Paleoarchean

3200 Ma

Mesoarchean

2800 Ma

Neoarchean

2500 Ma

Proterozoic:

2500 Ma

Paleoproterozoic

1600 Ma

Mesoproterozoic

1000 Ma

Neoproterozoic

542 Ma
