What is the full form of BODMAS
BODMAS: Bracket, of, Division, Multiplication, Addition and Subtraction
BODMAS stands for Bracket, of, Division, Multiplication, Addition, and Subtraction. It refers to the order of operations to solve an expression. It is also known as the Bodmas rule, which tells which process to perform first to evaluate a given numerical expression. It is also known as PEDMAS - Parentheses, Exponents, Division, Multiplication, Addition and Subtraction.
Brackets → ( or ) ← Parenthesis
Order → √ or X2 ← Exponents
Division → ÷ or ÷ ← Division
Multiplication → × or × ← Multiplication
Addition → + or + ← Addition
Subtraction → - or - ← Subtraction
It is easy to solve a basic summation which has two numbers and one single operation, such as addition, subtraction, multiplication, or division. But if there are many numbers and different operations in an expression then how will you decide from where to start and which operation to perform first, which to perform second and third and so on? For such expressions, we need BODMAS, as it clears the confusion and tells us the right sequence of operations: Division, Multiplication, Addition, and Subtraction.
20 x 5 + 40/2 = ?
Using the BODMAS rule, in the above expression, first, we need to perform division, followed by multiplication, and then addition. Such as:
