Rules of Order of Operations and Calculations

The rules of order of operations and calculations are essential in mathematics to ensure that expressions are evaluated correctly. Here's a detailed explanation of these rules:

1. Parentheses: - Parentheses are used to indicate which operations should be performed first. - Any operations within parentheses should be carried out before any other operations. - For example, in the expression (3 + 4) * 2, the addition inside the parentheses should be done first before multiplying by 2.

2. Exponents: - Exponents, or powers, indicate repeated multiplication of the same number. - When an expression contains exponents, these operations should be performed after any operations inside parentheses. - For example, in the expression 2^3 * 4, the exponentiation (2^3) should be calculated before multiplying by 4.

3. Multiplication and Division: - After parentheses and exponents are resolved, multiplication and division operations should be performed from left to right. - For example, in the expression 6 / 2 * 3, the division should be done before the multiplication, resulting in 3 * 3.

4. Addition and Subtraction: - Finally, after parentheses, exponents, multiplication, and division, addition and subtraction operations should be carried out from left to right. - For example, in the expression 5 - 2 + 7, the subtraction should be done first, followed by addition, resulting in 3 + 7.

These rules ensure that mathematical expressions are evaluated consistently and accurately, providing a standard order of operations for calculations.
