Level 51 combines number theory with complex analysis. The question is simple: Prove or disprove the Riemann hypothesis.

The disrespect in the thumbnail is unmeasurable.

As a uni student most of the levels past 21 are in wrong order but otherwise it is a great intuitive video for those teenagers interested in mathematics

[Atistatic]

The fun part is that the level 50 isn't even the deepest part of math, is just a beginning of the rabbit hole.

All answer:
Level 1:
1+1= 2
Level 2:
7*6=42
Level 3:
56/8=7
Level 4:

Level 5:
4.2+2.7=6.9
Level 6:
4.2*2.7= 11.34
Level 7:
25% of 80 equals 20
Level 8:
no, 253 isn't divisible by 3 because 2+5+3=10
and 10 is not a multiple of 3
Level 9:
1- x+5=12
2- 12-5=x
3- 12-5=7
x=7
Level 10:
1-the formula to get the perimeter of a rectangle is 2*L + 2*l with L=7cm and l=4cm:
2- 2L+2l= _Perimeter_
3- 2*7+2*4= _Perimeter_
4- 2*7+2*4=22
_Perimeter_ = 22cm²
Level 10.5:
1-to calculate the area of ​​a circle the formula is πr².
while knowing that the radius is half the diameter and that the diameter is 10cm: r=d/2=10/2=5
so the radius is 5cm.
2- πr²= _Area_
3- 5²π= _Area_
4- 25π= _Area_
5- 25π≈ 78.54
_Area_ ≈ 78.54cm²
Level 11:
1-since I have a 20% discount, $50 was 80% of the initial price.
2-to find the initial value you need to know the value of 1% so we do 50/80=$0.625, then we multiply it by one hundred: 0.625*100=$62, 5.
Level 12:
3^4=3*3*3*3=9*3*3=9*9=81
Level 13:
to know the chance of having an even number, is the number of positions where the die is even on the total number, which makes 3/6 or 1/2.
There is therefore 1/2 of having an even number.
* *_the explanations will be simplified_* *
Level 14:
1- x+y=12
2- 12-y=x; x= (12-y)
3- 3(12-y)- 2y =11
4- 36 - 3y - 2y = 11
5- (-5y) = -25
6- y=5
7- x = 12-5; x =7
x=7; y=5
*the rest will come later*

It's refreshing to see the honesty here. Thought I'd see everybody say, "50, easily." I recognized just about every topic, but my topology is weak. Honestly, I couldn't keep up with the ones I thought I could answer, but pretty sure I made it to the top half of questions. Maybe even past 30.

[muzza]

I'm ok up to 45, and would have to look a few things up past that. As a theoretical physicist, I always considered myself useless at maths. What some of my colleagues could do amazed me.

[Hexagy]

5:13 WHAT??! This is literally one of my favorite area's in mathematics😭

[vorpal]

Level 48 with a couple of exceptions, and I have a PhD in math... (my background before that was in computer science, so I have some holes in my knowledge of subjects like topology *smirk* and complex analysis)... but in combinatorial design theory, so when you said that people hate combinations and permutations, I was like,

[davethesid]

These levels aren't necessarily building on each other. So one can be at multiple levels at the same time.

[KeshavKartik-xrfw]

Bro had the most controversial thumbnail 🤐
( L at level 1 and light at level 50)

[Malekthebirb]

Sadly could only make it to 36 but hopefully my knowledge can evolve overtime! Love these type of videos it be wonderful if you could make more i'll be rewatching this video when i think i made a decent amount of improvement <3

[dean]

I don’t think that’s level 50 in the thumbnail unless you’re implying topology in some way in the realm of R^3 Euclidean space

[Nightmarebon]

Finally not dumb clickbait that called 1+1 hardest expressi9n

[defnes]

So basically you're responsible with all the first 35 levels at the age of 17 in Türkiye. (Which makes a 12th grader.)

[mbakumelanchton]

So embarrassed with myself. Being at level 26 makes me feel like I need to start all over again 😭😭

[ravindradixit]

I am class10 student from India. Because of early start of higher maths i am at level 31😊

[Jack-eis]

The divergence theorem is trivial first or near beginning of second year college math class content.

Level 42 is easier than level 38, though difficulty is relative i guess
