What is PEMDAS Rule?
PEMDAS is a useful method for remembering the sequence in which you should answer maths problems. It represents parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).
When you have a math problem with multiple operations such as addition, subtraction, multiplication, and division, PEMDAS instructs you to begin with parentheses, then exponents, then multiplication and division (whichever comes first from left to right), and finally addition and subtraction. It’s like a guide for solving math’s riddles! The use of PEMDAS is explained using the example below:
Suppose in a class two students A and B are asked to solve 11 – 2 × 2
Student A solved it as 11 – 2 × 2
= 7 × 2
= 14
Student B solved is as: 11 – 2 × 2
= 11 – 4
= 7
Both students solved correctly according to their understanding but only one is correct we will learn the correct way of solving such expression is explained using PEMDAS in this article.
PEMDAS Definition
PEMDAS is a math acronym that stands for
- Parentheses
- Exponents
- Multiplication and Division
- Addition and Subtraction
It denotes the sequence of operations in solving mathematical formulas. Parentheses are computed first, then exponents. Then, multiply and divide from left to right, followed by addition and subtraction. PEMDAS guarantees correct answers by prioritizing the order of operations in equations.
PEMDAS Rule
PEMDAS stands for Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction. It is a mathematical rule that is used to solve arithmetic problems effectively.
The order of operations is the rules that tell us the sequence in which the expression with multiple operations is solved. The order is PEMDAS: Parentheses, Exponents, Multiplication, Division (from left to right), Addition, and Subtraction (from left to right).
In this article, we will learn about the PEMDAS Rule with its order of operations, its applications, examples, and others in detail.
