I love how he explained what "approximately equal to" means but not "congruent to"

triangle > delta

I think the "triangle" simbol is a delta greek letter, meaning variation.

Thanks so much for uploading this lesson! I really appreciate it.

2:05 what a nice triangle I love triangle

2:11 ah yes my favourite mathematical symbol, π (pi)

0:04: Plus 0:13: Minus 0:19: Times / Multiplication 0:30: Division 0:38: Equals / Equal / Equal to 0:55: not equal to 0:58: approximately equals to 1:02: is approximately equals to 1:10: congruent to 1:16: Greater Than 1:23 Less than 1:33: Plus Or Minus

0:00 Mathematics Symbols 0:03 plus 0:05 For example: 0:07 5+2=7 0:12 minus 0:13 7-3=4 0:19 times sign or multiplication sign 0:23 5x2=10 0:28 division sign 0:30 10÷2=5 0:36 equal sign or is equal to Edit: 0:40 We say something is equal to or just equals. 0:45 For example: 10-2=8 0:52 is not equal to 0:56 is approximately equal 1:00 is approximately equal 1:02 We use it for a weak approximation. 1:09 is congruent to 1:14 greater than 1:16 8>4 1:23 less than 1:24 5

Δ > delta

Phi (known as Golden Ratio), Ampersand, Parallel, Intersection and Union of Two Sets, Perpendicular and For All are kind of strange......

Thank you so much!👏

I know the code is hello world Paste(2.39.5) Make(+5.5)

"minus" is often termed as "less", 5 less 2 equals 3 "empty set" is sometimes termed as "null set" but strictly speaking a null set means no set exists ‰ is per thousand Θ theta, representing the angular position of a vector ! factorial ∃ exists i could probably think of more, but that's enough

really hate that he only explained the simple ones

∈: is an element of ⊆: subset ⊂: proper subset ∃: exists Δ: change Δ(ABC): triangle ABC ∇: vector differential σ: standard deviation μ: mean/average ω: limit of a function, wright omega function, prime omega function (number of distinct prime factors of n), pearson cunningham function Ω: absolute infinity, prime omega function (total prime factors of n) Ψ: polygamma/digamma function, super golden ratio, reciprocal fibonacci constant Γ: gamma function, gamma distribution γ: euler mascheroni constant ⌈ and ⌉: ceil ⌊ and ⌋: floor W: lambert W function ℤ: set of integers ℚ: set of rational numbers ℝ: set of real numbers ℂ: set of complex numbers ℕ: set of natural numbers ℝ^n: n'th dimension ⊗: tensor product ⊕: direct sum ≃: asymptotically equal to, homopotic, homopoty equivalent P(): probability (in stats) ∣: conditional probability A B →: ray A B ∡: measured angle ': derivative of ∂: partial derivative ℵ: aleph ¬: not ∧: and ∨: or ℘: prime number ∏: product ∐: coproduct ⊢: graph intersection ⊣: graph union ⇌: equilibrium ∷: proportion nCm: binomial coefficient, read as "n choose m" nPm: number of permutations of m items chosen from a set of n items, i have no idea how to read this in a short way ∝: inversely proportional to this should be a good extension

Very useful lesson!

U = Union of two sets

a2 + b2 = c4

Plus 3^54 Minus 18^22 Times 40^56 Division 64^128 Trillion 10 and the UK and the UK and the UK and the US are all the same for the UK and UK nationals

next time please explain more about it

a lot of thank you

|| could also be concatenation, as well as parralel. Concatenation is a simple operation where you just put two number next to each other. For example, 3||7 = 37

Thanks for this video

Math is very interesting to learn

Thanks🙏🙏

Triangle is basically delta And sum of is sigama And golden ratio is phi

SUBSCRIBED?✅❤️

Πολύ ωραίο βίντεο, μπράβο.Απλώς αν θέλετε φτιάξτε το και στα Ελληνικά.

Thanks a lot

I tried + - × ÷ < > = () so for example why i put the equal because its simple it wasn't less than or greater than , its equal 3=3 !

I was hoping to see brief explanations for the less common symbols, and less explanation for the common ones.

I love thi's video

+plus -minus × Times ÷divide = Equal ≠not equal ≈ Approximately equal How do people finish?

Thanks.

This plus meaning to addition

Nice!

Thanks 👍👍👍👌🎉💐🎁♥️

My favorites are Lambda and Mu

Forgot the flipped E (there exists) and its opposite, a crossed flipped E (doesnt exist)

I've always heard the "braces" called curly/squiggle brackets and then the "brackets" are either just brackets or square brackets also why'd you disrespect delta like that edit: typically I've heard everyone call the Golden ratio phi

Interesting

He just turned 8 sideways for infinity

≈is approximately equal but isn't ~similar?

Good.

Thanks, so i draw it.

So, you explain and give an example of PLUS and MINUS but not CONGRUENT TO

1:34 my favorite part🎉🎉

Math with alphabet: a+b=c

also used for making emoticons ÷‿

Good job❤

+ - x ÷ = not equal to approximataly equal congruent to greater than

Good morning how's it going today 🌅 I speak 5 languages french English Spanish Portuguese creole, I want to speak Italian ❤

Thanks for all

You should have given an example of Congruence

Nice, thanks

Thanks

Square root: √

I need the definitions of all symbols please.

Empty set could be Ø

lim( ) x→∞ you forgot to introduce this.

Thank you

Thanks to your explain very nice. ❤🎉😊

Wait, wheres belongs to, or not belongs do?

I don’t like how you don’t explain what they mean 😢

+ - × ÷ = ≠ ≈ ~ *congruent not exist* > < ± *we don't know to make infinite* *not exist**not exist* => Ø
