Interval Notation Explained

Learn all about interval notation and learn how to write inequalities on a number line.
The key to writing intervals of inequalities on a number line is to use parenthesis for less than and greater than plus infiniti and brackets for less than and equal to and greater than and equal to.

I cover how to write interval notation examples from a number line which is very similar to writing interval notation from a graph. I include the interval notation symbols and how to apply them.
