Be careful when using Excel
In correct mathematical convention the expression
let A1 = 2 then
-A1^2 must yield
-A1^2 = -4
otherwise we would have to write
(-A1)^2 = 4
I share your opinion. But there are two Microsofts.
- for Microsoft#1, that is Excel: (-2^2 + 8) = 12
- for Microsoft#2, that is Visual Basic: (-2^2 + 8) = 4
Funny, isn't it?
