This video tutorial explains how to perform subtraction using expanded form. It begins by converting numbers into their expanded forms, such as turning 37 into 30 + 7 and 19 into 10 + 9. The tutorial then demonstrates the subtraction process, including borrowing when necessary, and concludes with the final calculation showing that 37 - 19 equals 18.

What is the first step in expanded form subtraction?

• Add the numbers together

• Write the numbers in expanded form

• Multiply the numbers

• Divide the numbers

How do you express the number 37 in expanded form?

What is the expanded form of 19?

• 100 + 90

• 19 + 0

• 10 + 9
