Title: Does NOT show the 'whole' problem-just the equation
Review: We bought this so that my son could see ALL the facets of adding and subtracting numbers, and especially to address a problem my first grader was having with lining up the numbers under the actual equation. Yes, this calucator shows the problem - but NOT the steps they teach in school. There are no 'figuring' steps, so he still has no idea how to carry over numbers, or borrow for substraction, or add a zero for double-digit addition. There's nothing showing him how the answer was found - just that there is an answer. He certainly knew this from the other calculators in the house. In other words, the only thing this calculator does is set up the problems in school format - it doesn't show how to solve it, step by step, which is what is required by the school. We are back to square one, and my son is no closer to solving a two-digit subtraction problem than he was before we bought this. But he's having fun pushing the buttons.
