$9625$ + $7986$
Start at the right of each number
Add the ones digits
$5$ + $6$ = $11$ 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.
$1$ + $2$ + $8$ = $11$ tens
Regroup the 11 tens as 1 hundred and 1 ten
Write the 1 ten in the tens column.
Write the 1 hundred in the hundreds column.
Add the hundreds digits next including the regrouped 1.
$1$ + $6$ + $9$ = $16$ hundreds
Regroup the 16 hundreds as 1 thousand and 6 hundreds
Write the 6 hundreds in the hundreds column.
Write the 1 thousand in the thousands column.
Add the thousands digits next including the regrouped 1.
$1$ + $9$ + $7$ = $17$ thousands.
Regroup the 17 thousands as 1 ten-thousand and 7 thousands.
Write the 7 thousands in the thousands column.
Write the 1 ten-thousand in the ten-thousand column.
Add the ten-thousands digits next which is the regrouped 1.
