Answer
$1004$
Work Step by Step
$798 + 206$
Start at the right of each number and add the ones digits
$8 + 6 = 14$ ones
Regroup the 14 ones as $1$ ten and $4$ ones
Write the $4$ ones in the ones column.
Write the $1$ ten in the tens column.
Add the tens digits next including the regrouped $1$.
$1 + 9 + 0 = 10$ tens
Regroup the $10$ tens as $1$ hundred and $0$ tens
Write the $0$ tens in the tens column.
Write the $1$ hundred in the hundreds column
Add the hundreds column next including the regrouped 1
$1 + 7 + 2 = 10$ hundreds
Regroup the $10$ hundreds as $1$ thousand and $0$ hundreds
Write the $0$ hundred in the hundreds column
Write the $1$ thousand in the thousands column
Add the thousands column next which is the regrouped $1$
$1$ thousand
The sum of the two numbers is $1004$
