FAQ
When do we regroup in 3-digit addition?
Whenever the ones add up to 10 or more (regroup 10 ones as 1 ten) or the tens add up to 10 or more (regroup 10 tens as 1 hundred).
How can you tell that 373 + 40 is greater than 373 + 23 without calculating?
Both start with 373, and adding 40 adds more than adding 23.
