How do you say 1<x<2?
Can you explain what interval notation is?
Interval notation is a way of representing an interval using its endpoints. The notation (a,b) represents the interval between a and b, excluding a and b themselves. The notation [a,b] represents the interval between a and b, including a and b themselves. And the notation [a,b) or (a,b] represents the interval including one endpoint and excluding the other.
