<h3>Overview of the Khan Academy Library</h3>

There's now a lot of content on the Khan Academy

so I thought I'd give your a quick overview video of how to think about the playlists

so the most basic playlist is the arithmetic playlist

arithmetic

and this is

it literally starts at one plus one equals two

and it moves

about as far as operations on decimals long division

things like that

the next most advanced playlist

is pre-algebra

if you're starting from scratch you might want to go in this order

pre-algebra

and pre-algebra as the name implies covers a lot of the foundational concepts for algebra

like adding, subtracting, multiplying, dividing negative numbers and fractions and exponents

and then we have several playlists that address

actual algebra so there's

an algebra playlist

there is an algebra playlist

there it is an algebra one playlist

algebra one playlist

and then there is a

there is a California

California standards

California standards and there's two playlists

California standards algebra one

and California standards algebra two

this just algebra playlist this is the the I would call this kind of the main

playlists covering algebra

when I just make an arbitrary algebra video I put it in this playlist

and I try to put it in order of

of of of of I guess advancement or of difficulty

this starts at the most basic algebraic equations

but with one caveat that

the the first few videos in this playlist are old videos these are some of the very first videos

that I did when I started making YouTube videos

and so they're not in HD, they're kind of rough I'm using Microsoft paint

they're they're not the the smoothest videos on the planet

but then obviously it also has a lot of new videos in this

and this algebra playlist covers both algebra one and algebra two

and I merged it into one playlist because frankly algebra two

has a lot of overlap or a lot of review with algebra one

this algebra one playerlist

this is worked examples from ck12.org's

ck12.org's open source algebra one book which

is a fairly comprehensive for covering the California standards and for those of you

who aren't in California what I say is

this is fairly comprehensive for algebra one and if you know algebra one by these standards

you're probably going to know the great majority of what you need to know

wherever you might be taking algebra

and frankly if you watch both of these playlists

I'm pretty sure you're going to be able to do any type of algebra problem that you might

see in any curriculum

math is math

now this is worked examples that you can and it's all done recently so all of these videos

are of of fairly good quality

and they're all in high definition

and you could just watch this algebra one playlist in order

and i'll just give you a little bit of warning the first sixteen videos

sixteen videos

the very first ones are kind of an overview so they move a little bit faster so if you

have a little bit

if his you're seeing algebra for the first time

and they seem like they're moving a little quickly

that's just because they're giving a survey of the course

and that's why..

and I did that just because that's the order that they were displayed in the book

but after those first sixteen video

starting with one step equation

it actually goes at a very moderate pace

and I do a lot of examples

and explain the concepts as I do the examples

so if you're just starting out want to learn algebra

what I'd recommend reviewing pre algebra, never hurts

then these are the two core algebra playlists

and you could start at either one

and find where you

where you feel comfortable

I would recommend

if you're some place in between you know a little bit of algebra, start at the beginning

watch every video and both of these playlists and if there's something just

super duper easy to you then you move on to the next video

but just make sure that you have all of your bases covered

now, these these videos right these playlists right here the California standards

these are just worked examples

based on the California standards

so after watching these you want to see more examples

it'll never hurt to watch these two playlists right there

now once you're done with algebra

you might want to look at the geometry playlist

you could probably start on the geometry playlist just with

pre-algebra but it's good to have that algebraic foundation there

and in most school systems

you take algebra one first

then geometry

then algebra two

so this is just a recommended path you might want to take

and then after geometry

you're ready to move into trigonometry

trigonometry

and after algebra you are also ready to move

'cos this playlist as I said it

goes through algebra two

after this you're also ready for pre-calculus

you're also ready for pre-calculus

and I'll write it at the same level as trigonometry because in most

in most

school systems you take trigonometry and pre-calculus

in the same year

usually your junior or your senior year

and then obviously after pre-calculus

and trigonometry

the next

you now are ready for calculus

and this is a fairly extensive playlist

it covers

calculus one, two and three

so differential integral and multi-variable and vector calculus

so in some places even you could almost say

even through calculus four

now we have another

another playlist that has the word algebra in it

but it is a much more advanced algebra

even though it might sound like a simpler algebra

it's called linear algebra

linear algebra

and if you've never seen algebra before do not watch this playlist it might sound

like "hey linear algebra is easier than non-linear algebra"

No, this is a mathematically rigorous course

that normally math and engineering majors take

in their, probably their sophomore year of college

and I would say that

you could start off if you have just a basic understanding of pre-calculus you could probably

you could probably start the linear algebra playlist

but I would recommend being fairly sophisticated mathematically

you probably want a little bit of your calculus out of the way, to start it

even though it is really algebra

it is mathematically more sophisticated than a lot of what goes on

in the calculus playlist

and in the calculus playlist once you're about halfway through

you don't have to go through the whole playlist

you're then ready for another advanced playlist that we have

and that's differential equations

differential equations

probably two-thirds of the way

through the calculus playlist you're probably

then ready for differential equations

another usually sophomore level course

for math and science and engineering majors

now everything else we have some

we have some probability and statistics

algebra is all you really need for that,

but I'll put it here because it's reasonably advanced

probability

there's a probability playlist

probability

and then there is a statistics playlist

they're obviously related

you might want to do the probability one first

but you don't have to

there's probability and there is a statistics

statistics playlist

we also have

a California standards geometry playlist

and that's worked examples just like that one over there

so i'll do that like that we also have

California

standards

California standards geometry

so you can

you can look at that if you want to see more geometric

worked examples

and then when you think about the sciences

we have physics

and the physics this is mainly I call them

applied algebra problems

so you might want to watch

physics right around after you finish algebra

there's only a few videos that require calculus

I'll eventually make an entire playlist

on calculus based physics

most of this it's just algebra based physics

so you're ready to go if you have a good solid understanding of algebra

and then the other sciences and the chemistry

uh it'd be nice to have algebra out of the way, pre algebra is probably enough for most of it

pre algebra is probably enough for most of it but algebra

if you have your algebra out of the way

then you're going to have no trouble at all with

the chemistry playlist

chemistry

and then biology does deal with a little bit of

of probability

and things like that so it wouldn't hurt

but that's actually that doesn't even require

too much mathematics or at least the mathematics

that I've diagrammed here.

we could put biology here

I guess the big take away is that

algebra's really important for

pretty much anything you want to do.

there's some genetics problems that require

some basic level and

and some population genetics of population

genetics problems that have some biology in it and then

all the finance and economics that also

I think it assumes

a base level of algebraic understandings

so the things on banking

things on banking you don't have to have the super advanced if you just go maybe

a halfway through one of these playlists you are probably ready for these

banking economics

economics

and finance

so hopefully that gives you a good overview of everything that's

on the Khan Academy

and let me know if you have any questions
