An interval as a set of numbers. Numbers = endpoints.
Split this into one inequality statement
This can be written as -4 < x < 7
Start with the left side which is greater than -4
No equal sign translates to (. Do not include the number -4
Evaluate the right side which is less than 7
No equal sign translates to ). Do not include the number 7
