The video tutorial explains the breaking apart method for subtraction, demonstrating both horizontal and vertical approaches. It emphasizes keeping the first number intact while breaking the second number into parts for easier subtraction. The tutorial also covers double-checking results using addition to ensure accuracy.

What is the first step in the breaking apart method when setting up a subtraction problem horizontally?

• Change both numbers

• Keep the first number the same

• Add the numbers together

• Multiply the numbers

When using the horizontal method, what is the first part of the second number to subtract?

• Thousands

• Tens

• Ones

• Hundreds

In the horizontal method, how can you make subtracting tens easier?

• Subtract all at once

• Add instead of subtract

• Ignore the tens

• Break it into smaller parts

What is the main difference between the horizontal and vertical methods?

• The method of addition

• The final answer

• The direction of subtraction

• The numbers used

In the vertical method, what should you do if you cannot subtract the tens directly?

• Add instead

• Multiply the numbers

• Skip the step

• Use regrouping

What is a strategy mentioned for subtracting ones in the vertical method?

• Skip the ones

• Multiply the ones

• Count backwards

• Add the ones

How can you verify your answer after using the break apart method?

• By multiplying the numbers

• By guessing

• By adding the result to the subtracted number

• By using a calculator

What is the purpose of double-checking your work in subtraction?

• To change the method

• To ensure accuracy

• To find a new answer

• To skip steps

Which method can be used as a primary way of subtraction according to the video?

• Break apart method

• Division method

• Multiplication method

• Traditional method

What is the final step in the break apart method?

• Subtract the tens

• Subtract the ones

• Add the numbers

• Subtract the hundreds
