Understanding Decimal Addition with Carry

Decimal addition with carry is a fundamental arithmetic operation used to add decimal numbers. When the sum of digits in a column exceeds 9, a 'carry' is propagated to the next column to the left. This process is similar to integer addition but includes handling the decimal point.

Example: To add 123.45 and 67.89:

• Start from the rightmost decimal place (hundredths place): 5 + 9 = 14. Write down 4 and carry-over 1.
• Move to the tenths place: 4 + 8 + 1 (carry) = 13. Write down 3 and carry-over 1.
• Move to the ones place: 3 + 7 + 1 (carry) = 11. Write down 1 and carry-over 1.
• Move to the tens place: 2 + 6 + 1 (carry) = 9. Write down 9.
• Move to the hundreds place: 1 + 0 = 1. Write down 1.

The sum is 191.34. This tool helps visualize each step of this process, making it easier to understand.
