My brother is always telling me about Y=mx+c and saying if i could learn it.

It involves charts and graphs, frankly, I've never liked those two words, my brother said you will a first but after a while it's ok.

But then again like ou said Melody, I don't want to get off topic.

Hi Melody,

I'm glad you posted on here.

Literally 2 minutes ago (when I came online) I searched this post to see if anyone can answer my question (in particular you!)

I was wondering this and i doubt that anyone would respond as it's a very old post.

Thank you for your explanation 

Now I can see the difference between combinations and permutations easily.

I have two questions. 

1). The word permutation, can it be used in a sentence the way combination is used? (I find it hard using the right words)

2). You said the answer is 1 (for example 1), however Alan got 1023 ?

Melody is correct,

It depends on how many elephants the homes can hold.

It can be 2 , 3 , 1 , 7 ...?

Argh 

Did 60 instead of 68, I hope you don't mind...

(I tried to do it this time right!)

$${\frac{\left({\mathtt{34}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{8}}}}\right){\mathtt{\,\times\,}}\left({\frac{{\mathtt{14}}}{{\mathtt{15}}}}\right)}{\left({\mathtt{1}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{30}}}{{\mathtt{60}}}}\right)}} = {\frac{{\mathtt{637}}}{{\mathtt{30}}}} = {\mathtt{21.233\: \!333\: \!333\: \!333\: \!333\: \!3}}$$

And i got it... Wrong. 

\\34\frac{1}{8}\times\frac{14}{51}\div1\frac{30}{60}\\\\
34\frac{1}{8}\times\frac{14}{51}\div1\frac{30\div30}{60\div30}\\\\
34\frac{1}{8}\times\frac{14}{51}\div1\frac{1}{2}\\\\
\frac{8\times34+1}{8}\times\frac{14}{51}\div\frac{2\times1+1}{2}\\\\
\frac{273}{8}\times\frac{14}{51}\div\frac{3}{2}\\\\
\frac{273}{8}\times\frac{14}{51}\times\frac{2}{3}\\\\
\frac{273\div3}{8}\times\frac{14}{51\div3}\times\frac{2}{3}\\\\
\frac{91}{8}\times\frac{14}{17}\times\frac{2}{3}\\\\
\frac{91}{8\div2}\times\frac{14\div2}{17}\times\frac{2}{3}\\\\
\frac{91}{4}\times\frac{7}{17}\times\frac{2}{3}\\\\
\frac{91}{4\div2}\times\frac{7}{17}\times\frac{2\div2}{3}\\\\
\frac{91}{2}\times\frac{7}{17}\times\frac{1}{3}\\\\\\
\frac{91\times7}{2\times17}\\\\
=\;\frac{637}{34}\\\\
\frac{637\times1}{34\times3}\\\\
=\;\frac{637}{102}\\\\
=\;6\frac{25}{102}

(In Lated i do copy and paste when repeating to save time, apart from that this was what i typed in)

Ok Melody, thanks for the example and racing to answer questions is a great opportunity, missing it would be dreadful. 

$$\\34\frac{1}{8}\times\frac{14}{51}\div1\frac{30}{60}\\\\
34\frac{1}{8}\times\frac{14}{51}\div1\frac{30\div30}{60\div30}\\\\

Subtraction is finding the difference between two numbers or more.

5-4= 1

The difference between 5 and 4 is 1.

There are many different synonyms for subtraction. 

E.g. Minus, take away, the difference etc...

Argh!

I just looked at that post rather then the entire latex.

I multiplied by 30 instead of 68 and added 68 instead of 30.

As for the latex, i can only divide the numerator and denominators and not numerator by numerator?

(The post count is useful thank you)

Ha, i thought it'll be like.

 2, 3, 4, 5, 6, 7, 8 ,9

Are all the numbers between 1-10.

8 is the amount.

$${\mathtt{8}}{!} = {\mathtt{40\,320}}$$

40320 combinations.

Haha!
