same formula two diff results?

[OneRanger]

In the attached image, you see the same formula twice differing only by putting ()'s around the negative number to which the exponent is applied. Is there something I should know here? I can see how this could really bite someone in the backside.

I believe this is because the Power operation has a higher precedence than the Negation operation. See the Prime's Algebraic precedence in the following post.
