 # Numbers

We have learned to read and write numbers up to 1000 in digits and words in our previous class. We also learnt about the smallest and greatest number of one, two and three digits.

Let us take a quick glance at these numbers.

 Number Smallest Number Greatest Number One-digit 1 9 Two-digit 10 99 Three-digit 100 999

In addition, in this chapter, we will be learning about the four digits, five digits and six digits numbers.

## Numbers from 1000 to 9999

We are familiar with the numbers till 1000.

We use numbers larger than 1000 on a daily basis. Hence, we need to understand numbers beyond 1000.

By adding one to each number starting from 1000, we get numbers beyond 1000.

As shown in the below table:

 1000+1=1001 One Thousand One 1001+1=1002 One Thousand Two 1002+1=1003 One Thousand Three 1003+1=1004 One Thousand Four 1004+1=1005 One Thousand Five 1005+1=1006 One Thousand Six 1006+1=1007 One Thousand Seven 1008+1=1009 One Thousand Nine 1009+1=1010 One Thousand Ten

Now, let us read and understand numbers from 1011 to 1100.

 1011 1021 1031 1041 1051 1061 1071 1081 1091 1012 1022 1032 1042 1052 1062 1072 1082 1092 1013 1023 1033 1043 1053 1063 1073 1083 1093 1014 1024 1034 1044 1054 1064 1074 1084 1094 1015 1025 1035 1045 1055 1065 1075 1085 1095 1016 1026 1036 1046 1056 1066 1076 1086 1096 1017 1027 1037 1047 1057 1067 1077 1087 1097 1018 1028 1038 1048 1058 1068 1078 1088 1098 1019 1029 1039 1049 1059 1069 1079 1089 1099 1020 1030 1040 1050 1060 1070 1080 1090 1100

Similarly, further numbers can be written as:

 1100 1200 1300 1400 1500 1600 1700 1800 1900 2000
 2000 3000 4000 5000 6000 7000 8000 9000

These are the four digits numbers.

The smallest number of four digits is 1000 – One Thousand

The greatest number of four digits is 9,999 – Nine Thousand Nine Hundred Ninety-Nine.

### Numbers beyond 9999

By adding one to each number starting from 9999, we get numbers beyond 9999.

9999 + 1 = 10,000 – Ten Thousand

99,999 + 1 = 100,000 – One Lakh.

999,999 + 1 = 10,00,000 – Ten Lakh

99,99,999 + 1 = 1,00,00,000 – One Crore

• The smallest number of five digits is 10,000 – Ten Thousand.
• The smallest number of six digits is 1,00,000 – One Lakh.
• The smallest number of seven digits is 10,00,000 – Ten Lakh.
• The smallest number of eight digits is 1,00,00,000 – One Crore
• The greatest number of five digits is 99,999- Ninety-Nine Thousand Nine Hundred Ninety-Nine.
• The greatest number of six digits is 999,999- Nine Lakh Ninety-Nine Thousand Nine Hundred Ninety-Nine.
• The greatest number of seven digits is 99,99,999- Ninety Nine Lakhs Ninety Nine Thousand Nine Hundred Ninety-Nine.
