Excel incorrect formula evaluation

[dcsaba89blk]

Calculating -(1-2)^2 which equals to -1

Wolfram Alpha correct answer: https://www.wolframalpha.com/input/?i=-%281-2%29%5E2

Google correct answer: https://www.google.com/search?q=-%281-2%29%5E2

Even VBA calculates it correctly: Range("A3") = - (1 - 2) ^ 2

But the Excel Function =-(1-2)^2 evaluates to 1 incorrectly.

Please fix it ASAP.

In Excel, the - operator has higher precedence than the ^ operator, so it evaluates the expression as

-(1-2)^2 = --1^2 = 1^2 = 1.

See Calculation operators and precedence in Excel 

We may not agree with this, but we cannot change it, except by adding parentheses:

=-((1-2)^2)

I doubt that Microsoft will be willing to change this, since it would break existing workbooks that depend on this behavior...

That is correct result. In data modeling (and Excel is data modeling tool) negation which looks like minus has higher priority compare to arithmetic operations

The order in which Excel performs operations in formulas (microsoft.com)

Thus for =-1^2 first negation is applied, after that exponent. Other words

=-1^2  =>   =(-1)^2    => 1

Same is for Google Sheets

That's differ from calculator result since in the latest there is no negation, only minus.
