help? i guess

[late scarab]

apparently this is supposed to be 23, and i for the life of me cannot spot what i did wrong

[arctic dove]

hmm shouldnt 18 - 27 be negative 9

[late scarab]

yeah the fuck

now i am even more lost

[jolly hedge]

$-3^2=-(3^2)=-9$

[gilded elbow]

Ephesians 2:8-9

[jolly hedge]

Not the same as $(-3)^2$

[gilded elbow]

Ephesians 2:8-9

[jolly hedge]

So you get $-18+27+18-4$

[gilded elbow]

Ephesians 2:8-9

[jolly hedge]

And you wrote a +2 and multiplied it

,calc -18+27+18-4

[gilded elbow]

Result:

23

[late scarab]

[jolly hedge]
