### Unit 3: Lesson 2

Subtracting decimals (tenths)

# Strategies for subtracting more complex decimals with tenths

Sal uses place value and decomposing numbers to subtract decimals to the tenths place, such as 2-1.2.

## Want to join the conversation?

• If want you to subtract 3-1.5 don't you add two zero's to the 3 then add a decimal between 3 and the two zero's? Or is there another way to do it instead of doing that?(adding the two zero's and adding the decimal between the 3 and the zero's) • why do we line up decimal points when adding and subtracting? • • • • I have two questions:

1) How do you create a time stamp?

2) So, is the easiest way to subtract decimals stacking? Or is there a better way? • for you first question,
I am not sure what you mean by creating a time stamp, but you could do the on a coding platform, I think.
There is no easy way and hard way. everyone has their own strengths and weaknesses. though many people say that stacking is a very efficient way of subtracting, other people say that there are other ways that they use that are very efficient. I think that stacking is very good in my opinion, but you might have a different one. so make sure that you find the one that you think is more efficient for you.

Me: do 10 - 2 and and a period in front of your anwser and boom your done with the first question. • • isnt doing the number line take more time then doing stacked up version?
