Type your credit card number, and "right to left" then multiply the second number of digits and type output below this figure, in the third line we write numbers that haven't stepped up as either numbers that therapies if less than 9 we write as if greater than 9 we put no. 9 and write output under the number as shown in the picture

The last step is to add numbers in the third line, if the result is divisible by the number 10 numbers are correct
