#### Work Step by Step

$306 + 848$
Start at the right of each number and add the ones digits
$6 + 8 = 14$ ones
Regroup the 14 ones as $1$ ten and $4$ ones
Write the $4$ ones in the ones column.
Write the $1$ ten in the tens column.
Add the tens digits next including the regrouped $1$.
$1 + 0 + 4 = 5$ tens
Write the $5$ tens in the tens column.
Add the hundreds column next
$3 + 8 = 11$ hundreds
Regroup the $11$ hundreds as $1$ thousand and $1$ hundred
Write the $1$ hundred in the hundreds column
Write the $1$ thousand in the thousands column
Add the thousands column next which is the regrouped $1$
$1$ thousand
The sum of the two numbers is $1154$
