I would love it if you explain why

 

 -sylvia

7800. :)

Would you like me to explain as to why?

Have a great day!!

You just add them together :). 

Sum means all together (:

Hayley, it says Estimate.

if you just sum it that would  be not answering the question ://

 

PLUS, you do not need to ask if people want an explanation - of course if it is a serious question then they want an explanation. ://  You do not have to give them the whol answer though if you don't want to. Sometime is is good to let them do some of the work :)

 

 

Estimate the sum of 3627 and 4187 to the nearest hundred

3637 rounds of to 3600

AND

4187 rounds off to 4200

36+42=78

 

so the sum is approximately 7800
