Answer
$15,954$
Work Step by Step
$9056$ + $78$ + $6089$ + $731$
Start at the right of each number
Add the ones digits
$6$ + $8$ + $9$ + $1$ = $24$ ones
Regroup the 24 ones as 2 tens and 4 ones
Write the 4 ones in the ones column.
Write the 2 tens in the tens column.
Add the tens digits next including the regrouped 2.
$2$ + $5$ + $7$ + $8$ + $3$ = $25$ tens
Regroup the 25 tens as 2 hundreds and 5 tens
Write the 5 tens in the tens column.
Write the 2 hundreds in the hundreds column
Add the hundreds digits next including the regrouped 2.
$2$ + $0$ + $0$ + $7$ = $9$ hundreds
Write the 9 hundreds in the hundreds column.
Add the thousands digits next.
$9$ + $6$ = $15$ thousands.
Regroup the 15 thousands as 1 ten-thousand and 5 thousands.
Write the 5 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.
1 ten-thousand
Separate each group of three digits with a comma.
The sum of the two numbers is $15,954$.
