Study Notes
Order of Operations
- The correct order of operations in mathematics is: parentheses, exponents, multiplication and division, and finally addition and subtraction.
Evaluating Expressions
- The result of the expression 4 + 5 * 2 - 3 is 11, following the order of operations.
- The value of 2 + 3 * 4 / 2 is 8, using the correct order of operations.
Purpose of the Order of Operations
- The purpose of the order of operations is to provide a standard procedure for evaluating mathematical expressions, avoiding confusion and ensuring consistency in mathematics and computer programming.
Precedence of Operations
- In an expression, multiplication is granted a higher precedence than addition, meaning it is evaluated first.
History of Exponents
- Exponents were introduced in the 16th century and were given a higher precedence than multiplication and division in the order of operations.
Use of Parentheses
- Parentheses are used in mathematical expressions to group numbers and operations, and to clarify the order in which operations should be performed.
Importance of Conventions
- Conventions for the order of operations exist in mathematics and computer programming to ensure that mathematical expressions are evaluated consistently and accurately, avoiding confusion and errors.
