$928 + 843$
Start at the right of each number and add the ones digits
$8 + 3 = 11$ 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 column next including the regrouped $1$
$1 + 2 + 4 = 7$ tens
Write the $7$ tens in the tens column.
Add the hundreds column next
$9 + 8 = 17$ hundreds
Regroup the $17$ hundreds as $1$ thousand and $7$ hundreds
Write the $7$ hundreds in the hundreds column
Write the $1$ thousand in the thousands column
Write the thousands column next which is the regrouped $1$
$1$ thousand
The sum of the two numbers is $1771$
