[SOLVED] Adding two Coloumns in Excel 2007

Hey all,

This might be way below the average mathematical discussion level at this forum but I do need help and the people here seem to know a crap load.

I am using Excel 2007 and i need to add values in cells between two coloumns with the output in a third coloumn in the same correspondig cell, Here's an example:

Coloumn A Coloumn B Coloumn C

1 2 ?

4 5 ?

4 6 ?

5 7 ?

Basically I would like to add the values in each cell of A and B and have the output in the corresponding cell in C, eg - 1 (A) + 2(B) = 3(C)

I would appreciate help with this.

Thanks
