The Full form of BODMAS is Bracket, of, Division, Multiplication, Addition, and Subtraction. BODMAS refers to the order of operations in Math to solve an expression. It is also known as BODMAS rule, which tells which process to perform first in order to evaluate a given numerical expression. It is not difficult to solve a basic summation in Math which has two numbers and one single operation to perform, such as addition, multiplication, subtraction, or division. But if in a summation, in which there are many numbers and different operations to be performed in an expression then it will be difficult for you to decide from where to start and which operation to perform first, which to perform second and third and so on.

So, we need BODMAS for such expressions as it clears the ides to solve an expression and tells us from where to start and the right sequence of operations: Division, Multiplication, Addition, and Subtraction. For example: 30 x 5 + 60/2 = x. By using BODMAS rule in the expression, first we need to perform division, followed by multiplication, and then addition. Such as: 60 divided by 2 is equals to 30, and 30 multiplied by 5 is equals to 150, and in the last 150 addition 30 is equals to 180, so the answer is 180.
