List of Mathematical Symbols in English | Math Symbols Vocabulary Words

Some commonly used mathematical symbols
"+" indicates addition
"-" indicates subtraction
"×" or "·" or "*" indicates multiplication
"÷" or "/" indicates division
"=" indicates equality
"≠" indicates inequality
"√" indicates square root

There are many more mathematical symbols than these, but these are some of the most commonly used ones.

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

[raulrueda]

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

[ttrep]

"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

[tasomenos]

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

[NmakesstuffImback]

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

[andrewgjennings]

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

[unnamedscribble-auttp]

really hate that he only explained the simple ones

[VehemenceOfTheDemigods]

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

[Oricorio-Pom-Pom]

|| 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
