The BODMAS Rule

Addition (+), subtraction (-), multiplication (?), division (?), and brackets ( ).

A very easy and very important rule required in day today life.

BODMAS rule is used to remember the order of operations to be followed while solving math?s equation. Its full form is B for Brackets, O for Order of powers, D for Division, M for Multiplication, A for Addition, and S for Subtraction. It means that the equation is to be solved, from left to right in this order. First, brackets are solved, then powers or roots, then division or multiplication and then at last subtraction or addition. If any equation has any operations missing, then also the same order is adopted. For example,

16/4+( 4*3), The expression has no minus, Then the same rule of BODMAS will be followed, Firstly we will solve bracket, then division and multiplication and at last addition.

Math is always about common sense and some standard rules. So, BODMAS is one of those standard rules for simplifying equations having several operators.

In mathematics, an equation has two basic components:

Numbers.
Operators.

Numbers are mathematical values used for counting They can classified as natural numbers, whole numbers, integers, rational numbers, irrational numbers, real numbers, complex numbers, imaginary numbers. 1 is always a UNIQUE number. Whereas an operator joins two numbers and produces an expression or equation. In math, the most common operators are Addition (+), Subtraction (-), Multiplication (*), Division (/). If the BODMAS rule is not followed, the answer can vary.

One way: 6 * 3 + 2 = 6 * 5 = 30,

Another way: 6 * 3 + 2 = 18 + 2 = 20.

So, in this equation, the second answer is correct, as in this the BODMAS rule is followed. Firstly Multiplication is done ( 6* 3) and followed by addition.

Therefore, BODMAS has to be applied, when there is more than one operation in a mathematical equation. There is a series of certain rules that need to be followed while applying the BODMAS method. This gives a right arrangement to create a single answer for every mathematical expression.

In case of a bracket, open it, then add or subtract the numbers. a + (b + c) = a + b + c, a + (b - c) = a + b - c

If there is a negative sign just open the bracket, multiply the minus sign with each number inside the bracket. a ? (b + c) ⇒ a ? b ? c

?If there is any number outside the bracket with no sign, as shown in the example multiply the number outside the bracket with each number inside the bracket.

Here, a(b + c) ⇒ ab + ac

One simple method to keep in mind for the BODMAS rule, is to carry out these stepladder:

Reduce the bare bones : Simplify brackets first

Perform division or multiplication (go from left to right)

Perform addition or subtraction (go from left to right)

Its time to solve some questions as in Maths- PRACTICE makes the man PERFECT.
