#### Work Step by Step

$746 + 905$
Start at the right of each number and add the ones digits
$6 + 5 = 11$ ones
Regroup the 11 ones as $1$ ten and $1$ one
Write the $1$ one in the ones column.
Write the $1$ ten in the tens column.
Add the tens digits next including the regrouped $1$.
$1 + 4 + 0 = 5$ tens
Write the $5$ tens in the tens column.
Add the hundreds column next
$7 + 9 = 16$ hundreds
Regroup the $16$ hundreds as $1$ thousand and $6$ hundreds
Write the $1$ thousand in the thousands column
Write the 6 hundreds in the hundreds column
Add the thousands digits next which is the regrouped $1$.
$1$ thousand
The sum of the two numbers is $1651$
