It is the study of:

- Numbers: including how things can be counted.
- Structure: including how things are organized, but also how they can be or could have been. This subfield is usually called algebra.
- Place: where things are, and spatial arrangement, including arrangements of spaces themselves. This subfield is usually called geometry.
