Hello, the numbers we see often, the disgusting numbers, and even the mathematics that explode just by looking at it, we are excited to meet the magic. The first one is the start button, and then the second to fifth are drawn with a magic math table, which is called Main, which is 4 times 4 and the number is in the table. There is a button to check whether there is a number or not. The button says "yes" or "no", and the last screen will show you the numbers you think.
