The present invention uses several blocks of rectangular parallelepiped numbers (0,1,2,3,4,5,6,7,8,9) and arithmetic operators (minus) + By printing ＜ ＞ and so on, it arranges forty or so blocks horizontally and vertically so that they are organized on the bottom of the puzzle. Combining the blocks makes it easy to learn the arithmetic operations of mathematics. Mathematical foundational arithmetic and mathematical instruction phrases with the advantage of easily combining units of numbers such as digits, tens, tens, hundreds, hundreds, millions, and billions of digits, and expose desired numbers and symbols. More than 40 cuboid blocks (3cm × 3cm × 1.5cm in volume) are organized into a single bottom puzzle surface and inserted into a rectangular cube (14cm × 15cm × 2.5cm) in a way to derive a task and answer. If you pick them up and turn them around, And while the basic arithmetic operations to dismantle reporting practice Shem, children will have lessons on mathematics arithmetic count nine of the cuboid block with easy access to, as well as repair concept count arithmetic of mathematics.
