If we want to write 1200000 in English, we can write it as "Twelve Lakh". So if there are 1200000 trees in a forest we can say ‘the forest has Twelve Lakh trees’. In order to write the number in its English word form, we need to understand the Indian numeric place value system.
In the Indian place value system, some of the places are named differently than in the international system. In the Indian system, the place value is named as follows
Place Value Name | Place Value |
Ten Crore | 108 |
Crore | 107 |
Ten Lakh | 106 |
Lakh | 105 |
Ten Thousand | 104 |
Thousand | 103 |
Hundred | 102 |
Ten | 101 |
One | 100 |
Now using the above table let's find the place value of every number in 1200000
Place Value Name | Ten Lakh | Lakh | Ten Thousand | Thousand | Hundred | Ten | One |
Digits | 1 | 2 | 0 | 0 | 0 | 0 | 0 |
Place Value | \begin{aligned} & 1 \times 10^6 \end{aligned} | \begin{aligned} & 2 \times 10^5 \end{aligned} | \begin{aligned} & 0 \times 10^4 \end{aligned} | \begin{aligned} & 0 \times 10^3 \end{aligned} | \begin{aligned} & 0 \times 10^2 \end{aligned} | \begin{aligned} & 0 \times 10^1 \end{aligned} | 0 \begin{aligned} &0 \times 1 \end{aligned} |
As we can see in the above table the number 1 is in the ten lakhs place and 2 is in the lakh place. We will not be using any of the zero place value names. When we write a number that is in one of the tens places ten lakh, ten crores, ten thousand, etc), we combine it with the number to the right and say the number together.
Therefore. 1200000 will not be written as Ten Lakh Two Lakh. We will combine the two numbers and it will be written as Twelve Lakh.
The number 1200000 can be mathematically expressed as following
\begin{aligned}
&1 \times \text{Ten Lakh} + 2 \times \text{Lakh} + 0 \times \text{Ten Thousand} + 0 \times \text{Thousand} +0 \times \text{Hundred} + 0 \times \text{Ten} +0 \times \text{One}\\
&=1 \times 1000000 + 2 \times 100000 +0 \times 10000 + 0 \times 1000 + 0 \times 100 + 0 \times 10 + 0 \times 1\\
&=1000000 +200000\\
&=1200000
\end{aligned}
