###### Notation Issue: Coordinates or Interval?

Unfortunately, the notation for an ordered pair looks exactly like interval notation for an open interval. Context will help you understand if $$(2,3)$$ indicates the point $$2$$ units right of the origin and $$3$$ units up, or if $$(2,3)$$ indicates the interval of all real numbers between $$2$$ and $$3\text{.}$$
