So I checked this on my smartphone first, and thought maybe the software is just shit.. So then I checked it on a Casio scientific calc, and both agree.

-3^2 = -9... And 9 != -9

.... Are all the calculators somehow wrong? What's the math rule I'm forgetting here...

[-] criitz@reddthat.com 5 points 4 months ago

I think your calculator is interpreting that as -(3^2) and not (-3)^2

Oh derp. Yep it is.

Was better when calcs had a +/- button.

And I remembered the math rule too.

GD I am just realizing how long its been since I did math in my head without a programming language..

I should take a math class again or something and refresh that knowledge.
