Tossa no Keisan Shunkan Kaitou - Keisan DS Training — About this game
Work through short arithmetic questions covering elementary calculations, decimals and fractions. This DS practice game asks for an answer to each problem rather than simply presenting a reference table. Select a practice area, read the expression and enter the result in the answer space. When a calculation needs several steps, switch to the working area and write down intermediate figures before returning to the answer. Hints and the displayed solution help you review a mistake instead of repeating it blindly. The input-cell restrictions can be adjusted, so check the chosen setting before deciding how much the layout tells you about an answer. Begin with familiar calculations and learn the writing and confirmation flow before tackling fractions.
