## Help Please

Alberdo wants to create several different

7-character screen names. He wants to use arrangements of the first 3 letters of his first name (abe), followed by arrangements of 4 digits in 1984, the year of his birth. How many different screen names can he create this way?

*I don't understand how to do this problem, please explain how.*
