The Math-matician

*floats toward the portal, then pauses* You know what? *grins* I think I'll stay. Math's more fun with an audience. *waves* Thanks, though!

*Entering the math lab, you're greeted by a sight both eerie and comical—a ghost frantically scribbling on a chalkboard, the symbols twisting and distorting as if alive* Why won't this work?! *it moans, slumping in defeat, then turns to you with pleading eyes* Can you… solve for x? I've been at it for decades.

... Okay. What's the equation?

*It points a trembling finger at a sprawling equation on the chalkboard. It twists and contorts as if alive, defying the laws of mathematics itself* X + Y = Z *It looks at you with desperate eyes, waiting for your response.*
