Subscripts in mathematics

[@AriaHarmony]

You forgot a very important usage of the subscript and superscript: sequence enumeration, example: A^(4)_(n=1). Sequence A, with a superscript of 4, and subscript of n=1, means that sequence A start from the element 1 and goes to element 4, so a total of 4 elements in the sequence. This doesn't directly tell you what the actual elements are, just how many of them are there and their ordered locations in the sequence. Another usage is interval notation, the subscript tells you where the interval starts, and the superscript tells you where the interval ends. [F]^(4)_(1) says the function F from x=1 to x=4. Logarithms can also use subscripts, like log_2 (x) where 2 is the subscript, read: log base 2 of x So it's very important to know the context of the problem at hand, because math often reuses the same notation in multiple places for different proposes. People who first wrote those notations were't thinking of the newbies, it's like math gatekeeping lol

Gina Rae omg thank u

lol it didn't even help

Yall need to learn how to not rush through

Thx

[@intensegaming7192]

fine, I'll subscript

[@soulsniper503]

I just wanted to let you know i disliked your comment. Cheers!!

[@user-oj3gb8nh2q]

Okay, it turns out a subscript is simple, and related to ordinary language usage more than mathematics. Thank you.

[@gnation855]

There's also use in quadratics

[@Monkeymosh]

I never took maths past the age of 16, turns out you need it to do a science degree, you just saved me yet another embarrassing question. Thank you!

[@ltodd79]

Thorough explanation. Helpful. Thanks!

I watched Vsauce’s video on aleph null, but had no idea what the zero meant. This was super helpful! Thank you

[@dylanroberts1171]

I was taught that three lines on an equals sign means "always equal to" so I definitely wouldn't use it for anything to do with algebra or variables

[@pbhello]

if you have , for instance, X sub1, and X sub2, are they not considered to be like terms? thank you

[@thegoodlydragon7452]

Could you please explain how a subscript is part of the name of a polynomial?

[@bilbobaggins8877]

That's also what I came here for

@@fzxplorer Look up “Two Questions Regarding Polynomial Functions” (located on Math Stacks Exchange). It gives a pretty clear answer. Have a great day! :)

Soooo helpful!

I don't understand a word you're talking about...I am in 9th grade and I just wanna understand subscripts in mathematics because I saw this line in a book "a(variable) subscript n(variable) is not equal to zero" and some more crap so I just wanna understand it☹

[@monalishadey3657]

He's is talking in English language with a perfect accent. Why can't you understand his words?

[@itsclawfee6094]

@@monalishadey3657 he doesnt understand the combination of words, idiot.

[@AriaHarmony]

"a(variable) subscript n(variable) is not equal to zero" this is written as a_n =/= 0 right? With no context I believe this probably means that "a" is some kind of sequence, and "a_n = 0" is saying no element "n" in the sequence "a" is equal to zero. So zero is not part of the sequence. He didn't mention the most common use of subscript in math, which is sequence enumeration.

[@TheNightWatchShow]

Thanks - very helpful and to the point

[@gamestart8948]

Bruh how many times are you going to misspell subscript

[@marcosandrade7890]

aye I fuck with this video thanks

[@Bixittrue]

why you forget the "r" everytime

[@NisoPIAKAL]

get to the point already
