In my computer class, we went over early computer devices, and the teacher gave us all an antique punch card and gave us a related problem to solve. Both it and the answer went right over my head. Help please!

Since you didn't give too many details of the problem to solve, I can't be very specific about the answer you want. In the OLDEN days, computations were often done in FORTRAN or COBOL or some other prehistoric language. The data input in the computer program specified that data had to appear in a certain portion of the card, and the data (sometimes) had to be in a certain format.
So hordes of lackeys would take data and go to the card-punching instrument and enter the data into the cards. The cards would be submitted for processing.

I can't exactly remember but it has 3 columns numbered between 0 and 2 and rows numbered between 1 and 9 such that if the punch is 0 and 1 then it means letter a, 0 and 2 is b. In column 0 with rows down to 9 its from a to i; column 1 with rows from 1 to 9 could signify letters j to r and so forth and so on.
