Word Problem

Suppose that license plates in a certain muncipality come in two forms: two letters (A....Z) followed by three digits (0...9) or three letters followed by two digits. How many different license plates are possible

I guess:
26*26 + 10*10

because there are 26 letters in the alphabets

you're on the right track, but multiply all of them, and you need three 10's, for the 3 digits

26*26*10*10*10
