Lesson 4: Regrouping whole numbers

# Adding whole numbers by their place values

Lindsay adds numbers like 19 thousands + 7 tens by thinking about their place values.

## Want to join the conversation?

• would 3 hundreds + 17 tens equal 470?
• yes, u r correct
• no offense but these are too long and non helpful!
• The thing is, they are helpful. How you may ask? They are important so that your school could see if your compatible for the next grade! I suggest you keep repeating videos so that you can see if you are making mistakes.
• this is easy a little?
• just keep trying until u get it i promise it wont take long
• looked at it a few now i think i know how to do this its just looks confusing
• why would the answer be 72,000
• because 22,000 is equal to 20,000+2,000 so 50,000+22,000=72,000
• i feel like the girls vids are longer then the guys....idk why tho lol
• I agree
