Notice that If you enter a number less than 0, the calculator will prompt you to enter a valid number.
It is because the calculator was made for multiplication of whole numbers. Therefore, the calculator assumes that you will enter a whole number, not integers, which include negative numbers or number less than 0.
Furthermore, if it says to enter a valid number, it will clear the box that contains a value less than 0
Lastly, "Enter a valid number" may mean that you have entered only 1 number.
Enjoy the calculator!
