Large Numbers

India developed a unique number system with ten digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) that has a positional

value system. It was later adopted across the world.

Mom, Indians are said to Yes, it is true that
have discovered a number Indians could write
pattern with a positional numbers much larger
value system, but how the
numbers were named earlier? than we could think
of. In Yajurveda, the
number Parardha
means 1 followed by
12 zeros; while in the
Valmiki Ramayana, 1
Mahaugh equals 1
followed by 55 zeros.
In the Jain religion,
Anuyogdwar book
mentions the multiple
of 2 as many as
96 times. Such big
numbers shows how
our ancient people
were capable of
doing mathematical
operations on
numbers.

We know that numbers are endless. By adding 1 to a number, we get the next number. In the

previous class, we have studied numbers up to 6 digits.

The numbers from 1–9 are one-digit numbers. There are 9 one-digit numbers.

The numbers from 10–99 are two-digit numbers. There are 90 two-digit numbers.

The numbers from 100–999 are three-digit numbers. There are 900 three-digit numbers.

Can you say how many four-digit, five-digit and six-digit numbers are there?

Now, let us discuss about the bigger numbers.

Look at the table to understand how large numbers can be obtained.
Greatest Number Adding 1 gives the next number Smallest Number

The greatest 6-digit number 999999 + 1 = 1000000 The smallest 7-digit number
i.e., 999999 i.e., 1000000
The greatest 7-digit number 9999999 + 1 = 10000000 The smallest 8-digit number
i.e., 9999999 i.e., 10000000
The greatest 8-digit number 99999999 + 1 = 100000000 The smallest 9-digit number
i.e., 99999999 i.e., 100000000
