Understanding the Standard Addition Algorithm

What is the primary purpose of the standard addition algorithm?

• To multiply large numbers

• To subtract numbers efficiently

• To provide a structured method for adding numbers

• To divide numbers into smaller parts

When using the standard algorithm, why is it important to line up numbers by place value?

• To avoid using a calculator

• To make subtraction easier

• To ensure each digit is added to the correct place value

• To make the numbers look neat

In the standard algorithm, what should you do if the sum of a column is greater than ten?

• Carry over the extra value to the next column

• Write down the entire sum in the same column

• Start the addition process again

• Ignore the extra value

Why do we carry over numbers in addition?

• To make the process faster

• To avoid errors in multiplication

• Because there is no room for numbers greater than ten in a single column

• To make subtraction easier

How can you verify the correctness of an addition problem?

• By multiplying the numbers

• By dividing the sum by one of the addends

• By subtracting one of the addends from the sum

• By adding the sum to one of the addends

What is the first step in solving 824 plus 158 using the standard algorithm?

• Add the hundreds place

• Add the tens place

• Add the ones place

• Add the entire numbers at once
