A certain type of combination lock has
3 dials: the first 2 dials each have settings for all the digits 0 through 9 and the third has settings for all the 26 capital letters of the alphabet. A combination consists of one setting from each of the dials. How many different combinations are possible?

Yep, thats wrong. THe real method is 10*26, since for every number there is 26 letters, so 26*10=260

I believe its 10*10*26.
in the first spot, you can choose from the numbers 0-9.
In the second spot (since they don't say you can't repeat, we have to assume that you can repeat digits) you can also choose between 0-9
In the final spot, you can pick from any of the 26 letters of the alphabet.
