Subject: Re: Addition error pattern

I agree that only asking the student will answer the question. Perhaps the confussion stems from the fact that: 0 X any number = 0 This is likely if the student has been introduced to multiplication, particularly 2-digit number multiplication. The error could be a misunderstanding of arithmetic algorithms half memorized without regards for their meaning. It could be also an inadvertent automatic performance, like driving part-way your usual route to work, when you were headed to the grocery store.
