Write the $9$ tens in the tens column.
Write the $1$ hundred in the hundreds column
Add the hundreds column next including the regrouped $1$
$1 + 4 + 0 + 4 + 6 = 15$ hundreds
Regroup the $15$ hundreds as $1$ thousand and $5$ hundreds
Write the $5$ hundreds in the hundreds column
Write the $1$ thousand in the thousands column
