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.

That's funny.
I would improve for clarity by putting spaces between
Write in one cell: =(- A1^2 + 8) .......... (result xxx(censored)
Write in another cell: =(8 - A1^2).............(result x(censored))
The result is same a yours, despite the spaces.
You may also enter negative numbers in A1 and also
decimal numbers, everytime a surprise.
Another Microsoft blunder?
