@jordyd @kimdanes @arisunz On the last day of grade 11 my math teacher had us march up and down in front of the dance studio in my high school to that mnemonic song
🎶 Negative B!
Plus-or-minus!
The square root!
Of B squared minus four-A-C! (all over 2A) 🎶
And it was to spite the dance teacher who sent students to dance (too loudly he thought) in front of his math classroom all year
