Default Mathematical puzzle (for all you Excel experts)


Hi


I have a mathematical puzzle that I cant solve.


In the table below, the inputs are the values in columns "A" and "B
and the desired output is column "C".


A B C


-3 -3 0
-3 +3 -6
+3 -3 0
+3 +3 +6
0 0 0


What on earth is the formula in Microsoft Excel that creates "C"?


With thanks

Clue:
If you strip the sign off "A" and then add "A" and "B" together
and then apply the sign afterwards, you get the correct
answer. But how the heck do you do this in msExcel ?
And/or isnt there a better way of doing the mathematics ? (!)


=SIGN(A1)*(ABS(A1)+B1)- Hide quoted text -

Yes, Greg I think you get the prize for the most *intuitively obvious*
solution.

i.e. in english, then
1. Keep the +ve or -ve "sign" of A
2. Then take A, and either add or subtract B from it
(irrespective of A's sign).

And yes, well done - that's exactly what I'm looking for !

thanks very much
