Common Subtraction Algorithm Errors in Teaching Mathematics

What is the error called when a student takes the smaller digit from the larger one instead of regrouping?

When regrouping from zero, what mistake does a student make if they change the 0 to a 9 without regrouping from the next digit to the left?

What is the error called when a student regroups from the leftmost digit instead of the digit immediately to the left?

If the top digit is 0, what mistake does a student make when writing down the bottom digit as the column answer?

What error occurs when a student skips regrouping in a column that requires it?

What is the mistake called when a student does not regroup across a 0, but changes it to a 10 instead of 9?

What error is made when a student decrements correctly during regrouping, but writes 0 as the answer instead?

When a student regroups from zero and changes the 0 to a 9, but fails to regroup from the next digit to the left, what common error is committed?

If a student takes the smaller digit from the larger one instead of regrouping, what is this subtraction algorithm error known as?

What is the mistake called when a student regroups from the leftmost digit instead of the digit immediately to the left during subtraction?

When a student writes down the bottom digit as the column answer, instead of regrouping, what error is being made?

What error occurs when a student does not regroup across a 0, but changes it to a 10 instead of 9?
