People Can't Seem To Figure Out This Triangle Puzzle On Twitter

I was never really good at math in school. But, thanks to some extra tutoring and endless work packets, I got a hold of how to compute with fractions and percentages.

Then, outta nowhere, algebra was dropped on my head and I struggled to understand whatever the heck that was. To my understanding, math was for numbers and English was for letters and sentences, why the heck were they combining them now? And before I could even get a grasp on algebra, then geometry comes into play and we're measuring shapes.

Freaking shapes and numbers? WHAT?!
