PEMDAS is an acronym used to help students remember the order of operations in mathematics. It stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. It is a useful tool for solving equations and understanding the way operations are performed in mathematics.
Understanding PEMDAS
When solving mathematical equations, it is important to follow the order of operations to ensure that the equation is solved correctly. The acronym PEMDAS helps to remember this order. Parentheses are always evaluated first, followed by Exponents, Multiplication, Division, Addition, and Subtraction.
When parentheses are used, the equation inside the parentheses is evaluated first. The parentheses serve as a grouping symbol and can enclose any type of equation. Exponents are evaluated next. Exponents are a shorthand way of writing repeated multiplication and can be written as a number, variable, or expression raised to a power.
Multiplication and Division are evaluated next and are performed in the order they appear in the equation. For example, if the equation includes both multiplication and division, the multiplication is done first. Finally, Addition and Subtraction are evaluated in the order they appear.
Applying PEMDAS
To apply PEMDAS, it is important to first identify the operations that are present in the equation. Once the operations have been identified, the equation can be solved by following the order of operations.
For example, consider the equation 6 + 2 x 5. In this equation, the operations are addition and multiplication. To solve this equation, the multiplication must be performed first. This can be done by using the PEMDAS acronym, which reminds us that multiplication is evaluated before addition. By following the order of operations, the equation can be solved correctly. The answer to the equation is 16.
