The order of operations is a set of rules that dictates the correct sequence in which to evaluate a mathematical expression. The acronym PEMDAS is often used to remember this order:
1. **Parentheses**: Calculate expressions inside parentheses first.
2. **Exponents**: Evaluate exponents (powers and roots, etc.) next.
3. **Multiplication and Division**: Perform all multiplication and division from left to right.
4. **Addition and Subtraction**: Finally, perform all addition and subtraction from left to right.
It's important to note that multiplication and division are performed at the same level; if both operations appear in the expression, you work from left to right. The same applies to addition and subtraction.
Some people also use the acronym BIDMAS or BODMAS, where "B" stands for "Brackets" and "O" for "Orders," which refer to the same concepts as parentheses and exponents.
