There are multiple ways to explain + and -. One is that + and - are abstractions from everyday experience. If you have a group of n things and another groups of m things, and you lump them together, you will now have n + m things in your group. Similarly, if you have n things and take away m things, you now have n - m things. However, if you are unsatisfied this this explanation, there is a way to formalize arithmetic (+ - * /), which mathematicians use. en.wikipedia.org/wiki/Peano_axioms This explains exactly how + and - work and how you can define them just using logic.
The surface of his face is a continuous manifold ( ignoring the nostrils ,mouth, ears etc.), but nowhere differentiable - in other words, not smooth .. .hahaha...
What's with the porn music at the start LMAO
I asked myself the same question.
🤣🤣🤣🤣
Mathematics is sexy.
Peter Sarnak rocks, he's brilliant!
Very insightful and inspiring. I remember him from the BBC Horizon documentary Fermat's Last Theorem.

Nooo 😭
No offense but he looks like a Dishonored character.
Love is blind to you mathematicians...
To me, is not ☀️
U + me = love :)
Nobody on earth has explain to me where do Zero and 1 come from...
everyone just assumed it’s right 🙄
Goodness!
Set theory answers all these questions you are asking. What mathematicians mean by 0,1, +, - etc
The natural numbers are assumed to exist (we must start from somewhere) but the basic operations are defined from set theory
@@tomkamikaze one can indeed prove existence of natural numbers.
@@ramveersingh2591 True we need the axiom of specification to extract unwanted elements from the set implied by the axiom of infinity
I need to correct that
Good training?
😂
Where + and - come from?
Dude?!
Not even how an egg came to happen, yet... they’ve got Particle Physicists 😓🤦🏼♀️🙄

Your comment is irrelevant, unnecessary and disrespectful.
