Does Excel Calculate Using Order of Operations? (PEMDAS/BODMAS)
Ever wondered exactly how Excel handles complex formulas? Does it follow the same mathematical rules as your high school math teacher? The answer is a resounding **yes**. Excel strictly adheres to the order of operations, often remembered by the acronyms PEMDAS or BODMAS.
But what does this really mean for your spreadsheets? How can you be sure your calculations are accurate? This guide will break down how Excel interprets formulas, show you the exact order it follows, and provide a practical tool to visualize the calculation process.

How Does Excel Handle the Order of Operations?
When you type a formula into Excel, like =(5+3)*(10/2)-1, it doesn’t just evaluate it from left to right. Excel follows a strict mathematical hierarchy to ensure accuracy in complex calculations. This hierarchy is universally known as **PEMDAS** or **BODMAS**.
PEMDAS vs. BODMAS
While the underlying principle is the same, the acronyms differ slightly depending on your region:
- **PEMDAS**: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)
- **BODMAS**: Brackets, Orders (powers and square roots), Division and Multiplication (from left to right), Addition and Subtraction (from left to right)
Both systems tell Excel to handle
