Work Step by Step
$5718$ + $5623$ + $7436$
Start at the right of each number
Add the ones digits
$8$ + $3$ + $6$ = $17$ ones
Regroup the 17 ones as 1 ten and 7 ones
Write the 7 ones in the ones column.
Write the 1 ten in the tens column.
Add the tens digits next including the regrouped 1.
$1$ + $1$ + $2$ + $3$ = $7$ tens
Write the 7 tens in the tens column.
Add the hundreds digits next.
$7$ + $6$ + $4$ = $17$ 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.
Add the thousands digits next including the regrouped 1.
$1$ + $5$ + $5$ + $7$ = $18$ thousands.
Regroup the 18 thousands as 1 ten-thousand and 8 thousands.
Write the 8 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.
