Summary:The utility model provides arithmatic sticks for children which belong to a children intelligence toy having easy playing method. The utility model has a simple and solid structure, and can do arithmetic operations of two integers. The utility model can be formed by the following modes. Ten decahedral square cylinders with same shape are arranged on a convex rib shaft with a handle.
