Decimal Subtraction Concepts

Matt and Mr. J demonstrate how to subtract decimals by aligning the decimal points and using placeholder zeros. They walk through the borrowing process step-by-step to solve the problem 26.4 - 13.58, resulting in 12.82. The video concludes with a quick review and a link to a more detailed explanation.
