Be careful when using Excel

I think this message can be of interest for those using Excel for antenna
calculations.
Write in one cell: =(-A1^2 + 8) Note: the exponent of A1 is 2 (and not
2+8=10) because Excel performs squaring before summing
Write in another cell: =(8 - A1^2)
They look pretty much the same
But give A1 any non-zero value and see what happen.

I see it give the correct answers!!!
eg when A1 =2 the first formula =12 and the second =4
-2 squared =4
So 4 plus 8 = 12
2 squared =4
So 8 - 4 = 4
8 - (2 squared) = 4
