### What are Numbers?

A number is an arithmetic value expressed by a word, symbol, or figure that represents a specific quantity and is used in counting and calculating.

Numbers can be single-digit numbers, two-digit numbers, three-digit numbers, and so on.

Example: 4 and 5 are single-digit numbers. 34 and 99 are two-digit numbers whereas 897 and 100 are three-digit numbers.

### Number Names

In an alphabetical format, number names are used to represent numbers.

Each number is denoted by a distinct word.

### Place Value of a Digit

To write a number in English, we must first understand the place value of each digit in the number.

Place value refers to the position or location of a digit in a number.

Each digit has a specific place in a number.

When we represent the number in its general form, the position of each digit will be expanded.

Units, tens, hundreds, thousands, ten thousand, and so on are the order of place value of digits of a number from right to left.

Example: See the below figure for understanding the place value of each digit in the number 1468.

**Place value **

### Example of Number Names

Number (in figures) | Number (in words) |

100 | One hundred |

105 | One hundred five |

110 | One hundred ten |

203 | Two hundred three |

299 | Two hundred ninety-nine |

8000 | Eight thousand |

8001 | Eight thousand one |

8740 | Eight thousand seven hundred forty |

### Comparing Numbers

Identifying a number that is smaller or greater than the rest is referred to as comparing numbers.

For example, if we compare numbers from a hundred to two hundred then a hundred is the smallest number and two hundred is the largest number.

We can compare numbers in a variety of ways using counting or counting the number of digits, using place values of the numbers, and so on.

### Patterns

Numbers can form interesting patterns.

To find the pattern, we must examine the difference between one number and the one that follows it. For example, consider a pattern 5, 10, 15, 20, 25,…. . In this, the difference between two consecutive numbers is 5.

There can be two kinds of patterns: Forward counting pattern and Backward counting pattern.

A forward counting pattern means numbers will increase in sequence. For example, 2,4,6,8,10 and so on (here in the pattern we are adding two in each term).

A backward counting pattern means numbers will decrease in sequence. For example, 100, 98, 96, 94, 92 and so on (here in the pattern we subtract two from each term).

### Counting by 10s, 50s, and 100s

The count of tens is simply grouping the ten numbers together to form one unit of ten. For example, the first count would be 10, followed by 20, 30, 40, and so on.

Count of fifties is grouping the fifty numbers together to form one unit of fifty. For example, the first count would be 50, followed by 100, 150, 200, and so on.

A count of hundreds is grouping a hundred numbers together to form one unit of a hundred. For example, the first count would be 100, followed by 200,300,400, and so on.

Similarly, we can count numbers in 1s, 2s, 5s, 20s, 500s, and so on.

This method of counting has an important real-life application. Say if you have to pay Rs. x to a shopkeeper you need to divide Rs. x in different groups of 1s, 2s, 5s, 10s, 50s, 100s, and so on. ( that is in different denominations of Indian rupees)

Question 1. How many tens are there in 180?

Solution: Let’s begin by writing all 10s

10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170 and 180.

By counting the above numbers we observe that eighteen tens are there in 180.

Question 2. How will you pay Rs 467 to a shopkeeper? (assuming you have only 100 rupees notes, 10 rupees notes, and one rupee coin)

Solution: We can write 467 as 400 + 60 + 7. Hence we can pay the shopkeeper using four hundred rupees notes, six-ten rupees notes, and seven one rupee coins.

**Question 3. How many rupees are there in the below image?**

**Rupees**

Solution: Above image has

Four hundred rupee notes, which will amount to rupees 400.

Six ten-rupee notes, which will amount to rupees 60.

Two one rupee coins which will amount to two rupees.

Hence total amount is Rs (400 + 60 + 2) = Rs 462

### What is a Century?

In sports, a century is a score of 100 in a game of cricket.

There are different types of centuries present which are mentioned in the table below:

Type of century | Score |

Half-century | 50 |

One and a half-century | 150 |

Double century | 200 |

Triple century | 300 |

Quadruple century | 400 |

A century is another name for a race of 100 yards or 100 miles.

2, 5, 8, 11, 14, __, __
