Calculating rows

I need help in excel. I want to calculate total sums by multiplying 2 rows
then follow by addition. I have the rough idea how to do but the problem is
very complicated because I have 53 column of data. The 1 trying to do is like
this $B$1*B3+$C$1*C3+.....+$BZ$1*BZ3. Is there a simpler way of doing?
