BODMAS

BODMAS:

 As per the BODMAS rule, we have to calculate the expressions given in the brackets first. 

The full form of BODMAS is Brackets, Orders, Division, Multiplication, Addition and Subtraction. 

Hence, the second preference in BODMAS is given here to the orders or exponents (xn). 

 Later we perform the arithmetic operations (÷, ×, +, -). 

We will solve examples based on this rule in the below sections.


It explains the order of operations to be performed while solving an expression. 

According to the BODMAS rule, if an expression contains brackets ((), {}, []) we have first to solve or simplify the bracket followed by ‘order’ (that means powers and roots, etc.), then division, multiplication, addition and subtraction from left to right. 

Solving the problem in the wrong order will result in a wrong answer.

Tips to Remember BODMAS Rule:

The rules to simplify the expression using BODMAS rule are as follows:

  • First, simplify the brackets
  • Solve the exponent or root terms
  • Perform division or multiplication operation (from left to right)
  • Perform addition or subtraction operation (from left to right)

Note: The “O” in the BODMAS full form is also called “Order”, which refers to the numbers which involve powers, square roots, etc. Check the examples below to have a better understanding of using the BODMAS rule.

  Example 1Example 2
BBrackets5 × ( 7 – 3) = 5 × 4 = 2024 ÷ ( 8 – 5 ) = 24 ÷ 3 = 8
OOrders7 + 22 = 7 + 4 = 1110 – 32 = 10 – 9 = 1
DDivide9 + 12 ÷ 3 = 9 + 4 = 1310 – 6 ÷ 2 = 10 – 3 = 7
MMultiply10 ÷ 2× 3 = 10 + 6 = 169 – 4 × 2 = 9 – 8 = 1
AAdd4 × 3 + 5 = 12 + 5 = 172 × 7 + 8 = 14 + 8 = 22
SSubtract10 ÷ 2 – 2 = 5 – 2 = 39 ÷ 3 – 1 = 3 – 1 = 2

Fibonacci Sequence

  Fibonacci Sequence The Fibonacci Sequence is the series of numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ... The next number is found by adding up the two numbers before it: the 2 is found by adding the two numbers before it (1+1), the 3 is found by adding the two numbers before it (1+2), the 5 is (2+3), and so on! Example: the next number in the sequence above is 21+34 =   55 It is that simple! Here is a longer list: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418, 317811, ... Makes A Spiral When we make squares with those widths, we get a nice spiral: Do you see how the squares fit neatly together? For example 5 and 8 make 13, 8 and 13 make 21, and so on. This spiral is found in nature! See:  Nature, The Golden Ratio, and Fibonacci The Rule The Fibonacci Sequence can be written as a "Rule" (see  Sequences and Series ). First, the terms are numbered from 0 onwards like this: n = 0 1 2 3

VEDIC MATHEMATICS

VEDIC MATHEMATICS VEDIC MATHEMATICS IS THE TRICKS FOR FAST CALCULATIONS   ·         Vedic Mathematics  is a collection of Techniques/Sutras to solve mathematical arithmetics in easy and faster way. It consists of 16 Sutras (Formulae) and 13 sub-sutras (Sub Formulae) which can be used for problems involved in arithmetic, algebra, geometry, calculus, conics. ·         Vedic Mathematics is a system of mathematics which was discovered by Indian mathematician  Jagadguru Shri Bharathi Krishna Tirthaji  in the period between A.D. 1911 and 1918 and published his findings in a  Vedic Mathematics Book by  Tirthaji Maharaj ·         Veda is a Sanskrit word which means ‘Knowledge’. ·         Using regular mathematical steps, solving problems sometimes are complex and time consuming. But using Vedic Mathematic’s General Techniques (applicable to all sets of given data) and Specific Techniques (applicable to specific sets of given data), numerical calculations can be done very fast.
