Description: Sal uses place value and numbers in expanded form to subtract decimal to hundredths, such as 8.38 - 4.54. Let's say we wanted to compute eight and 38 hundredths minus four and 54 hundredths. I would view this as the same thing as eight and 38 hundredths, and then I would subtract four and 38 hundredths. The reason why I pick 38 hundredths is that will cancel out, it'll take away these 38 hundredths.
