How many 4 digit numbers can you write if you can use only digits 1 and 2?

It’s 24−2=14. The first term indicates the way of choosing four independent digits, each one having two possibilities (being either 1 or 2); the −2 takes out 1111 and 2222. The number of 4-digit numbers with only digits 1 and 2 is 24=16, and 2 of them are 1111 and 2222, which should be excluded.
