Addition Using the Standard Algorithm

Front

What is the standard algorithm for addition?

Back

The standard algorithm for addition involves aligning numbers by their place values (units, tens, hundreds, etc.), adding each column starting from the rightmost column, carrying over any value greater than 9 to the next column.

How do you add multi-digit numbers using the standard algorithm?

Back

To add multi-digit numbers using the standard algorithm, write the numbers one above the other, align them by place value, add starting from the rightmost column, carry over if necessary, and continue to the left.

What is carrying in addition?

Back

Carrying in addition is the process of transferring a value from one column to the next when the sum of that column exceeds 9.

How do you check your addition for accuracy?

Back

To check your addition for accuracy, you can reverse the process by subtracting one of the addends from the sum to see if you arrive at the other addend.

Front

What is the importance of place value in addition?

Back

Place value is crucial in addition as it determines the value of each digit based on its position, ensuring that numbers are added correctly according to their respective columns.

Front

What happens if you forget to carry over in addition?

Back

If you forget to carry over in addition, the final sum will be incorrect, as the value that should have been transferred to the next column will not be accounted for.
