Lila forgot the security code for her apartment building. the code is two different digits followed by a capital letter. how many different possible codes are there?

There are 10 digits in which she can choose from for the first digit of her code. That is from 1 to 0. After using one of the digits, she can only have 9 digits for the second character in her code. Lastly, there are 26 letters she can choose from for the third character. Multiplying the numbers we get,
                                10 x 9 x 26 = 2340
