Traditional Addition Method:
The traditional method sums two number by adding their single digits from right to left. If the sum of the digits is greater than 9, then a carry over occurs. The carry over is placed over the next digit group. The carry over is then included in the next groups sum.
The addition algorithm working from left to right is as follows:
1) Add the two digits and carry over if it exists.
2) If the sum from step one is greater than 9 place the ones in the same column and carry over the tens value to the next column.
3) Repeat until the left most digit group has been processed.
Note: This calculator will show zero digits preceding a number for clarity.
Note: The right most digit group will not have a carry over value.
