Math Is Fun Forum

Wow ! Only four days after I posted this link, *POOF!* it's gone !! Counton.org is restructuring, and I don't see any of the pages that I had referred to previously.

I have checking the videos out because of this link, and they are working for me. That one particular dude (younger one) cracks me up now and then. I like the videos because they cut to the chase, yet still address the formula(s) that are presented in classrooms, so you can compare their version with the original, and therefore will make better sense.

I think that if you are here for a little while, and don't get banned, you become a member.

To MathisFun or Ricky or any other Mod, am I correct?

Jane ! You are so smart ! Not just a math whiz ?? Wow, impressive

I thought K2 was in the Himalayas.

3 feet long = 36 inches, so the bathroom floor width equals:

36 inches / 2 inches per side per tile = 18 tiles wide. Put that amount aside for now, ok?

Next, the floor is 2 feet wide.

24 inches wide divided by 2 inches per side per tile = 12 tiles wide.

So for the bathroom floor we now have:

18 tiles wide and 12 tiles long. Multiply that out for your answer

First problem:

Start with the 7-3, that equalling 4
Next do 2^3 = 8

So now you have:

9 + 6 x (4) x 8

Next, multiplication from left to right (don't add the 9 yet):

6 x 4 x 8 = 192

Now add your 9:

192 + 9 = 201

Follow the same processes for the next one and you can see where the 275 comes from

Hi G ! Welcome

Hi Myka-X !

I am a musician - guitar player, mostly, but I also play bass and keyboards. I'll check out your site - nice guitars !

Hi Rachel, welcome ! Ditto to Pravin's post, there are some extremely helpful and friendly people here. See ya here soon

Thank you Krassi I appreciate the help !

Please correct me if I am wrong..

If a curve on a graph is "cut" by a secant line (I didn't know what word to use), we could call one end of the secant point a and the other a+h, as h representing the difference in distance on the X axis of the two points.

If the line that is tangential to point a is pivoted on point a, thus decreasing the distance of a+h, this distance a+h could be termed a+h', the first derivative of a + h. Is there anything correct about this?

What I am trying to accomplish here is understanding derivatives better, and that's when I came across "e". Am I on the right track at all?
