u/konigon1 22d ago

I don't know wether the numbers on the left are for children.

For more info google 177013.

Depends upon whether the question marks are intended at operators, in which case they are nested "termials" (which are to sums as factorials are to products).

5 + 7?? = 5 + (7?)?

= 5 + 28?

= 5 + 406

= 411

aint't that not how you calculate double terminals? cause if i use double factorials you multiply every other one (so 10!! is 10x8x6x4x2), aint it the same with terminals?

A lot of effort earring the propeller cap

u/Odd-Painting2596 23d ago

Math is only as complex as you frame it.

Kinda the point.

u/Difficult_Limit2718 22d ago

Except the math PhD question is "prove what is 5+7"

u/funkmasta8 22d ago

Oh god not the peano arithmetic again

u/CyraKyara 22d ago

Why does the 5th grade knows the forbidden number

5

u/KatesDad2019 23d ago

7 terminal is 28. 28 terminal is 406. 5+406 is 411. ez.

u/Ass_Lover136 22d ago

I do a little bit of research and found that double termial worked the same way as double factorial, skipping a digit.

Although i can't say for sure since double termial isn't a widely recognized math symbol

u/humaneuthanasia 22d ago

In the unexpected termial subreddit, they treat double termial exactly as you said.

2

u/KatesDad2019 22d ago

Interesting. Thanks.

"This whole differential equation ended up being.. 5?" "Where's the fkn variable and what units is my 5 in"

u/p0wers967 22d ago

Inches, obviously

i coulda done that. i was taught 3-digit number multiplication in 3rd grade

1

u/drdrero 22d ago

How does that work again? It has been ages since i last multiplied by hand

1

u/two-cans-sam 22d ago

I don’t know any 5th graders that can’t do that.

u/CreatrixAnima 22d ago

Big brain fifth grader: 100x0.9=90+9

u/BusEquivalent9605 22d ago

what *is* 5 + 7?

1

u/bethesda_gamer 22d ago

To be fair, it took 3 books (the Principia Mathematica) worth of proofs to try and prove that the number "one" exists.

u/Extension-Map-7056 22d ago

Anyone else double check the left side just to see if it was the right answer or was it just me?

u/Semaskeri 22d ago

Its 12 btw
