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 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.
