5756 plus 8643 equals what?
The easiest way to calculate the answer is to use column addition. We start by adding in the ones column. Six ones and three ones is nine. Moving into the tens column, we have five tens plus four tens, which makes nine
tens. Seven hundreds and six hundreds makes 13 hundreds, or 1300. So we write the three hundreds in the hundreds column and exchange the thousand in
the thousands column. Now we just need to add in the thousands column. Five plus eight is 13, plus the one we exchanged makes 14. 5756 plus 8643 equals 14399.
