# 'sum of A and B' or 'A added to B'?

Hello,

Is it correct to speak of 'the sum of A and B' or 'the sum of A added to B'? Maybe both are correct?

To me, "the sum of A added to B" is redundant. The sum of A and B is the result of adding A to B, as opposed to something like the product of A and B, which would be multiplying A and B.

"The sum of A and B," "A added to B," "A plus B," "the total of A and B ..." - but, as JamesM posted, not "the sum of A added to B." That could only be correct in a broader context, such as "the sum of A added to B and C added to D," which would mean (A+B)+(C+D). Arithmetically, that's exactly the same as A+B+C+D, but there are situations in which we might want to speak of the two intermediate sums.

Thank you both. I suspected as much, but wasn't sure. As it happens, it is in the broader context of a formula written out, but I think it will still be clear if I put "the sum of A and B".
