In this section, we will revisit the topic of PEMDAS also known as the Order of Operations. We previously learned that the order of operations was used to tell us which order to perform each operation when evaluating a mathematical expression. Here we will include a few new scenarios that involve integers. How can we remember the order of operations? Most people memorize the acronym PEMDAS and the saying: "Please Excuse My Dear Aunt Sally".

PEMDAS:

1) Look for parentheses or grouping symbols, none are present

2) Look for exponents, we have 5

25 - 7 • -4

3) Look for multiplication or division, we have 7 • -4, which is -28

25 - (-28)

4) Look for addition or subtraction, we have 25 - (-28), which is 25 + 28 or 53

PEMDAS:

- P: Stands for Parentheses - this is where we begin, work inside of any parentheses or grouping symbols
- E: Stands for Exponents - we next evaluate all exponent operations
- M, D: Stands for Multiply or Divide - working from left to right
- A, S: Stands for Addition or Subtraction - working from left to right

^{2}, which is 2525 - 7 • -4
