Book Free DemoThe greatest one-digit number is \(9\). Adding \(1\) to the greatest one-digit number will result in \(9+1 =10\). That is, it results in the smallest two-digit number.
The greatest two-digit number is \(99\). Adding \(1\) to the greatest two-digit number will result in \(99+1 =100\). That is, it results in the smallest three-digit number.
Proceeding in this way, we can have the following table.
Greatest number | Adding 1 | Smallest number |
\(9\) | \(+1\) | \(=10\) |
\(99\) | \(+1\) | \(=100\) |
\(999\) | \(+1\) | \(=1000\) |
\(9999\) | \(+1\) | \(=10000\) |
\(99999\) | \(+1\) | \(=100000\) |
\(9999999\) | \(+1\) | \(=1000000\) |
\(9999999\) | \(+1\) | \(=10000000\) |
Thus, the resultant pattern becomes,
Greatest single\((1)\) digit number \(+ 1 =\) smallest \(2\)-digit number
Greatest \(2\)-digit number \(+ 1 =\) smallest \(3\)-digit number
Greatest \(3\)-digit number \(+ 1 =\) smallest \(4\)-digit number
Greatest \(2\)-digit number \(+ 1 =\) smallest \(3\)-digit number
Greatest \(3\)-digit number \(+ 1 =\) smallest \(4\)-digit number
and so on.
Important!
Recall the following:
\(1\) tens \(= 10\) ones
\(10\) tens \(= 1\) hundreds \(= 100\) ones
\(1\) thousand \(= 10\) hundreds \(= 100\) tens
\(1\) lakh \(= 100\) thousands \(= 1000\) hundreds
\(1\) crore \(= 100\) lakhs \(= 10,000\) thousands
