We can use place value to subtract decimals. We stack the decimal numbers on top of each other in vertical form, lining up the decimal points. We can insert trailing zeros to the right of a decimal without changing its value, so all of the decimals will have the same amount of digits. We learned to model decimal subtraction with base-ten blocks, or a quick drawing, in video 3.6. We can make a quick drawing to check our subtraction. We subtract decimals just as we would subtract whole numbers, except we must line up the decimal points to make sure we're subtracting the correct digits. We can use an estimation to know if our actual difference is reasonable. If we don't line up decimal points correctly, we may subtract the wrong digits. In video 3.2, we learned to read and write decimals in standard form, expanded form, and word form. We can write an equation from word form. When an equation is given in sentence form, we can stack the decimals in vertical form on scratch paper to subtract them. We solve a word problem involving subtraction of decimals.
