because 1 is toobig

With addition, you need to regroup in the event that there are more than 10 ones or 10 tens. In a subtraction, you must regroup whenever there are insufficient ones or tens to subtract.

because sometimes the total is too big

When the lower digit is greater than the upper one.

3 addends mean 3 numbers. Regroup I believe means carry over. So I'm thinking something like 36+29+12=
