FAQ
What does 'no carrying' mean in column addition, and why start with it?⌄
No carrying means the ones column sum stays below 10, so no regrouping is needed — students can focus on column alignment and basic addition before adding regrouping complexity.
Why is column alignment important in two-digit plus one-digit addition?⌄
Misaligning the one-digit number with the tens instead of ones column is a common error that produces wildly wrong answers — alignment practice prevents it.
What is the correct procedure for adding a 2-digit and 1-digit number in columns?⌄
Write the ones digit of the 2-digit number above the 1-digit number, leave the tens column with only the tens digit, then add ones first and bring down the tens.
