Math Is Fun Forum

thank you very much....

it is undefined, I want the advices about both boys\girls
I didn't talk to anyone, the problem is : I have an article I must write about that, cause director of the press service need from me this article
so he told me write about : how you learn the child to clean up, do you understand me? sorry for my bad language

I actually don't know what kind of methods did they use, but in my childhood I was see my father always like to pick up dirt and move it to wastepaper basket, and I influenced by it and Imitate this behavior without awareness,

(( I wrote about this in my article but it is not enough I need more information please ))

so do you have any information?

he did not specify, do you have a simple algorithm?  he use java language be he don't want a program to run it
he want a simple algorithm,

is there?

I do that

for example :

7 ,  I add +1 to number 7

it will be "8"  , when I do that I say after :

8%2=0  if it is true then the number is prime!

and the 7 it prime cause it is true

is that method right? or wrong?

I know, but from where did you the x2-x1? I mean how did you het the change in x,

may you tell me that

I just want to get the slop in any any point in the line any point I like and I want that not just from this table,

I try some numbers between number 146 and 138 and I mention that as an example, but take this : 145-131/8-4 = 3.5

so now it is between two points and it is 3.5 not 2,

can I know why that is happen? maybe I can find the slop of simple functions but I want to know further and further than that,

just tell me the reason please.

yes..,,,, I Edited and fix the example ...

but what is mean ( shrink towards  zero)

what we shrink? and is that between one point or two

and,

what is that

x changes from x to x+Δx?
y changes from f(x) to f(x+Δx)?

are we calculate something by this rule?

yes

no I don`t
