In this lesson, we will revisit the order of operations. Now, we will include problems with integers and grouping symbols such as the absolute value operation. First, we will think about how to use PEMDAS or BODMAS correctly. We will state the order of operations here:
1) Parentheses or grouping symbols.
2) Exponents or radicals
3) Multiplication or Division (from left to right)
4) Addition or Subtraction (from left to right)
