## Operations with rational numbers

## Binomial theorem

**Combinatorics**

## Permutations

## Permutation without Repetition

A permutation is an arrangement, or listing, of n distinct objects in which the order is important.

Total number of permutations in case of n elements:

Pn=n⋅(n−1)⋅(n−2)⋅…⋅2⋅1=n!

**Example:**

In case of 4 elemts: {a,b,c,d}:n=4,P4=4!=4⋅3⋅2⋅1=24n=4,P4=4!=4·3·2·1=24

**Rhombus** : A quadrilateral whose four sides are equal and the opposite sides are parallel to each other is called a rhombus.

- The perimeter of rhombus = 4 × side
- Area of rhombus = base × height

In this quadrilateral the opposite angles are equal and its diagonals bisect each other at right angles.

**Circle**: – A circle is a locus of points in which the distance between each other point revolving from a fixed point is the same, the fixed point is called the center of the circle.

**Radius**: The straight line joining the circumference of a circle to the center is called the radius.

**Diameter**:- The line passing through the circumference of the circle and touching the vertices of the other circumference of the circle, which passes through the center of the circle, is called the diameter.

**Chord**: – A line segment joining any two points on the circumference of a circle is called a chord of a circle.

**Sector**: The figure made up of two radii of a circle and an arc under it is called a radius.

**Segment**:- The area enclosed by the chord and arc of a circle is called a segment. Here the shaded part is the segment.

**Concentric Circl**e:- If two or more circles have the same center, then those circles are called concentric circles.

## maths formula sheet : Maths formula

- Area of circle = r2
- Circumference of circle = 2πr
- Area of the radius (arc AB) × r (where = central angle)
- Area of the rings of concentric circles = (r2 – r2)
- The perimeter of the semicircle = (π 2) r

*Vadic Mathematics Tricks*

### 1. Squaring Of A Number Whose Unit Digit Is 5

For example Find (55) ² =?

Step 1. 55 x 55 = . . 25 (end terms)

Step 2. 5x (5+1) = 30

### 2. Multiply a Number By 5

Even Number:

2464 x 5 =?

Step 1. 2464 / 2 = 1232

Step 2. add 0

The answer will be 2464 x 5 = 12320

Odd Number:

3775 x 5

Step 1. Odd number; so ( 3775 – 1) / 2 = 1887

Step 2. As it is an odd number, so instead of 0 we will put 5

The answer will be 3775 x 5 = 18875

Time to check your knowledge:

Now try —- 1234 x 5, 123 x 5

So our answer will be 3025.

### 3. Subtraction From 1000, 10000, 100000

For example:

1000 – 573 =? (Subtraction from 1000)

We simply subtract each figure in 573 from 9 and then subtract the last figure from 10.

Step 1. 9 – 5 = 4

Step 2. 9 – 7 = 2

Step 3. 10 – 3 = 7

So, the answer is: (1000 – 573) = 427

### 4. Multiplication Of Any 2-digit Numbers (11 – 19)

There are 4 steps to get the result:

Step 1. Add the unit digit of the smaller number to the larger number.

Step 2. Next, multiply the result by 10.

Step 3. Now, multiply the unit digits of both the 2-digit numbers.

Step 4. Then add both the numbers.

For example: Let’s take two numbers 13 & 15.

Step 1. 15 + 3 =18.

Step 2. 18*10 = 180.

Step 3. 3*5 = 15

Step 4. Add the two numbers, 180+15 and the answer is 195.

(a – b)^{4} = a^{4} – 4a^{3}b + 6a^{2}b^{2} – 4ab^{3} + b^{4})

a^{4} – b^{4} = (a – b)(a + b)(a^{2} + b^{2})

a^{5} – b^{5} = (a – b)(a^{4} + a^{3}b + a^{2}b^{2} + ab^{3} + b^{4})
