We obtain 10 lakhs, which is equivalent to 10*100 thousand.
As a result, 1000 thousand equals one million.
A thousand consists of 10 hundred. And each 100 is made of 10 tens. That is, 10*10 is equal to 100.
Now, one million is equal to a thousand 1000s; if we take 1000 such millions, then they make a billion. So one billion has 1000 million hence, 1000 million* 1000 = 1 Billion. Thousands of such Billions make one Trillion. Hence, a thousand multiplied by a thousand and once again multiplied by a thousand will give one trillion. It will look like 1000 * 1000 * 1000 = 1 trillion.
