Well let's break it down:

  • 🍔 + 🍔 + 🍔 = 18
    • 3🍔 = 18
    • 🍔 = 6
  • 🍔 + (🍟 • 🍟) = 5
    • 6 + 🍟^2 = 5
    • 🍟^2 = -1
    • 🍟 = I
  • 🥤^🍟 - 🥤 = 3
    • 🥤^i-1 = 3
    • 🥤 = 3^1/(i-1)

Simple!

Wait, what happened in the second to last bullet point? You can't convert a power like that when subtracting (you can when dividing).

It's like you'd convert "2^4 - 2" into "2^(4-1)", which gives two different results (14 vs 8).

For those curious, I threw 🥤^i - 🥤 = 3 into wolfram.

🥤 ≈ -2.97983 + 0.0388569 i... or 🥤 ≈ 0.27972 - 0.748461 i...

You're right, idk what I was thinking there 😕

[–] name_NULL111653@pawb.social 14 points 2 years ago

I think they're saying no one can give the real answer to this... which is technically true because the answer is imaginary.

[–] Rin@lemm.ee 13 points 2 years ago (1 children)

you forgot the ± when square rooting:

🍟 = ±i

this is because i × i = -1 and -i × -i = -1

[–] anti_antidote@lemmy.zip 3 points 2 years ago

Bah, yes I forgot about that

[–] ichmagrum@feddit.de 10 points 2 years ago* (last edited 2 years ago)

🍟 = I

Don't you mean 🍟 = i?

And just like that, I'm back to junior high grumbling about the concept of imaginary numbers.

Fuck you, y'all made up! 🤣

[–] anti_antidote@lemmy.zip 1 points 2 years ago

Lol I didn't quite get my math right, but it still involves imaginary numbers. Fun fact! Any 3D game you've played in the past probably quarter century doesn't just use 1 dimension of imaginary numbers, but 3 to represent 3D rotation! Quaternions are difficult to visualize since it's a 4-dimensional quantity but they're perfect for representing rotation in 3D space without suffering from gimbal lock like rotation matrices.

I fucked around, and this is what i got:

🍔 + 🍔 + 🍔 = 18

=> 🍔 = 6

🍔 + ( 🍟 × 🍟 ) = 5

🍟² = -1

=> 🍟 = ±i

(🥤^ 🍟) -🥤= 3

case 1: (🥤^ i) -🥤= 3

case 2: (🥤^ -i) -🥤= 3

at this point, i just used wolfram to get both:

=> {

🥤 ≈ -2.97983 + 0.0388569 i,

🥤 ≈ 0.27972 - 0.748461 i

}

Curiously, case 1 and case 2 return the same 2 values...

Correction, 99% of European people can’t solve this. For Americans this just a regular breakfast

[–] alphapuggle@programming.dev 6 points 2 years ago

Y'all bitch about math class but it you replace x, y & z with🍔🍟🥤 and suddenly you're all doing math for fun

A quarter pounder with cheese

[–] edinbruh@feddit.it 2 points 2 years ago

You mean a cheese royal?

Math now supports Unicode variables! The progress we all need.

Looks like you need a refill.
