Order of Operations in Arithmetic Expressions

In arithmetic expressions, the order of operations is crucial to ensure the correct evaluation of the expression. The standard order of operations is often remembered using the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

1. Parentheses: Operations within parentheses are performed first. 2. Exponents: Exponentiation is the next operation to be performed. 3. Multiplication and Division: These operations are performed from left to right. 4. Addition and Subtraction: Finally, addition and subtraction are performed from left to right.

For example, in the expression 1 + 2 * 3, the multiplication (2 * 3) is performed before the addition (1 + result of 2 * 3).

In the expression (1 + 2) * 3, the addition inside the parentheses is performed first, and then the multiplication.

This order of operations ensures that arithmetic expressions are evaluated consistently and accurately.
