i love math so much i have a proof for this: consider (a/b)*(c/d) = n let a/b = v c/d = t division is the oppsosite of multiplication by definition so (a/b)*b = a a = v*b c = t*d so a*c = v*b*t*d v*t = n so a*c = n*b*d (a*c)/(b*d) = (n*b*d)/(b*d) (a*c)/(b*d) = n n = (a/b)*(c/d) we are done the proof note : i took as a fact that multiplication is commutative and associative
Hi, Mr. Gibson, I was wondering if you could rearrange your chemistry course playlists in a chronological order? I noticed that some of them aren’t, so it got confusing to not watch the lectures in order. Thanks in advance!

Great video , great explanation 👍
i love math so much i have a proof for this:
consider (a/b)*(c/d) = n
let a/b = v
c/d = t
division is the oppsosite of multiplication by definition
so (a/b)*b = a
a = v*b
c = t*d
so a*c = v*b*t*d
v*t = n
so a*c = n*b*d
(a*c)/(b*d) = (n*b*d)/(b*d)
(a*c)/(b*d) = n
n = (a/b)*(c/d)
we are done the proof
note : i took as a fact that multiplication is commutative and associative
Thanks.....❤

Your videos on linear algebra and calculus are not complete
When you buy the courses they are fairly complete.
@@rosskious7084 okay, thanks!
Calculus has 3 parts
Calculus 1: Intro to Limits and derivatives
Calculus 2: Integration techniques
Calculus 3: Multivariable Calculus
