How to defeat a dragon with math - Garth Sundem

Having trouble remembering the order of operations? Let's raise the stakes a little bit. What if the future of your (theoretical) kingdom depended on it? Garth Sundem creates a world in which PEMDAS is the hero but only heroic when in the proper order.

Lesson by Garth Sundem, animation by Mark Phillips.

It's perfectly understandable e wasn't a good ruler.
He was completely irrational

0:50
7 ate 9

7 : "I have to eat 3 squared meals every day!"

Multiplication: Leader
Division: Lancer
Parenthesis: Big Guy
Exponents: Smart Guy
Addition: Heart
Subtraction: Sixth Ranger (Because of his lack of definition during the whole naming sequence)

Oh my god guys, at 0:50,  
A 7 is eating 9
7 ate 9
7 8 9

I think dividing by 0 is equivalent to the nuclear bomb.

I love how subtraction is protrayed as this small little docile character, but it's really the only one that can effectively reduce the sequence of numbers into zero.

Now everytime I solve a math equation, I will recall how the six musketeers defeated a mathematically huge dragon.

[paulcastillo]

Dragon: Lol try to kill me
÷ Sign: *_Divides dragon by 0_*
Dragon: *_OH GOD

[DriRedX]

That was the weirdest TED-Ed video I've ever watched.

[McTofuwuerfel]

Funny how people say "just multiply by 0" when deriving the constant dragon would have been as effective but more elegant.

"Throw a calculator"



AND PUT X 0

[sauceke]

+ = health potion (heal you and hurt the dragon)
- = knife (really sharp)
× = shuriken ( poisonous)
÷ = dart ( poisonous)
( ) = gauntlet ( spiked)
What is your weapon

0:51 OMIGOSH!! Anyone notice the PUN
SEVEN eight(ate) NINE

this will definitely help me in Skyrim.

In the UK, here, we use BODMAS. Brackets, Order (Exponents or Square Roots), Division, Multiplication, Addition and Subtraction.

[htlchtlc]

It's easy. Just turn the ( ) into a 0 and put it after division guy. By dividing the dragon by 0 the universe breaks and the dragon is kill. Simple geometry.

[jantulinja]

i always use the pemdas strategy in boss battles

[beehivemind]

*PEMDAS, THERE'S ANOTHER SPOT!!*

[Ray-xqcx]

0:56 Are we all just gonna ignore the fact that the narrator just casually mentioned the land of pi was an anarcho-syndicalist commune?

Truly Ted Ed’s weirdest video by far.
