Understanding the Order of Operations
The order of operations is a set of rules that determines the sequence in which different operations should be performed in a mathematical expression. The commonly used acronym PEMDAS helps students remember this sequence:
1. Parentheses
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)
This section will delve into why understanding the order of operations is crucial for students.
