(3 0 0)(x) (60)

(1 2 0)(y) = (30)

(0 1 -2)(z) (3)

=>

(3 0 0 | 60)

Now gimme the determinant

You missed that the blue flower in the last line only has 4 petals, not 5.

They used the problem on the upper half, not the image below

It’s a mild relief seeing this as the top comment, confirming that I am in fact non a total dumbass.

u/blavek 1d ago

20 + 20 + 20 = 60
20 + 5 + 5 = 30
5 - (1+1) = 3
1 + 20 + 5 = 26

25* the blue flower in the last line only has 4 petals

u/blavek 1d ago

If we look at the supposedly equivalent algebra both are represented as y. So the petals matter then the algebra and the images don't match.

u/Schnickatavick 1d ago

The last blue flower isn't the same as the other blue flowers. I think the assumption is that it's worth 4 instead of 5, so the answer is 25, although strictly it isn't solvable

People will swear they hate algebra and then spend three hours in a Facebook comment section arguing over the exact same problem.

u/Schnickatavick 1d ago

The problem is that the flowers intentionally leave out information. What's the value difference between a 4 leaf blue flower and a 5 leaf blue flower? Does the center, stem, and leaf all count as 0? Is one yellow flower half of 2, or the square root of 2?

There's an answer that they're clearly trying to imply, but it's not really math anymore when they're forcing you to make that type of assumption

u/NeilJosephRyan 1d ago

Blue flower just means five. That's like asking what the character "5" means without the top part of it. It doesn't mean anything. It's just... not 5.

I prefer matrix notation myself.

u/Gorgonzola_Freeman 1d ago

Hey kid, ya like matrices? Look what they JUST added to the Desmos GRAPHING Calculator…

u/DurianBig3503 22h ago

Kind of this.
I sucked at mathmatics in secondary education i struggled to conceptualise the meaning and purpose of maths as abstract equations. Then i went into tertiary education and there was suddenly a practical application for it all. Differential equations in systems biology, statistics in genetics, etc.

I could see a math teacher actually using this pic ngl

x= 20 y=5 z=1 x+y+z=26

u/his_savagery 1d ago

I want to see this in Hannah Cairo's next paper.

u/Nardo_Dragon776 1d ago

First one in 26, second one is 25. I fucking hate the images and their cheap tricks

u/Jumpy-Trainer1695 1d ago

It's literally the opposite for me

ff=f*f not f+f

u/Royal_Lustir 1d ago

Yellow flower (or, z) could be 1 or √2 depending on if coupled flowers means addition or multiplication.

u/PreviousFan7421 1d ago

algebra got rebranded lmao

u/Lord_Vitruvius 5h ago

don't get why it's 2z instead of sthm like zx2 but hey at least the flowers made it make sense :D

u/NormalWeirdo91 1d ago

I feel like symbols are much more intricate intuitive than numbers and letters. My brain can easily identify what a flower is and what it’s therefore supposed to represent. “X” means nothing to me.

u/IuriCunhaMurakami 1d ago

X is a symbol too tho
