The value of pi is approximately 3.14159

During the French revolution, to make calculations easier for their largely uneducated populace, the revolutionaries in their distain for intellectuals made a proclamation that the value of pi is hereby redefined to be exactly 3.00000000

While this made calculations easier, it made for very bumpy cart wheels!

True story!      Well, almost true!!

Thanks Melody

I got the answer d=66

I'm not sure if I did it correctly and if that's the answer :/

Q: whats in-between 63 and 99?

A: lots of numbers, an infinite lot of numbers, in fact.

Here are half a dozen examples:

63.11

63.1100000000000000000000000000000000000000000000000001

66

80.3^•

98.99999999999999999999999999999999999999999999999999

98.999999999999999999999999999999999999999999999999991

Do all your homework exercises, then just for fun find another textbook and do some practice exercises from it, too! 

By choosing the exercises you do, rather than all the time doing only what the teacher sets you to do, you are taking control of your learning, and in no time at all you'll realize that you have come to own that subject. Make it yours!!!!

˙ˍ¯þ ʼß -¯þ´.

subtract 2x from both sides

Add 15 to both sides

That should just about do it  :)

So are you going to fix your post ?

Ahhh.... I was to focused on latex i thought it was 4/2... I kew tnere was something funky with that question!LOL

MG,

$$2\div 4 \mathbf{\;\ne \; 2}$$

Your LaTex is great but you have to get the answer right too.     LOL   :)))

\\y=8\times \left(\frac{2}{4}-\frac{\frac{6^3}{2}}{15}\right)\\(2 \div 4 =2)\\y=8\times \left(2-\frac{\frac{6^3}{2}}{15}\right)\\6^3=(6\times6\times\66)=216\\216 \div 2= 108\\y=8\times \left(2-7.2\right)\\2-7.2=-5.2\\y=8\times-5.2=-41.6\\y=41.6

What i typed down.

$$\\y=8\times \left(\frac{2}{4}-\frac{\frac{6^3}{2}}{15}\right)\\(2 \div 4 =2)\\y=8\times \left(2-\frac{\frac{6^3}{2}}{15}\right)\\6^3=(6\times6\times\66)=216\\216 \div 2= 108\\y=8\times \left(2-7.2\right)\\2-7.2=5.2\\y=8\times-5.2=-41.6\\y=41.6$$

So many mistakes...

I meant -5.2.  2 - 7. 2 = -5.2. And i forgot to show 108/15=7.2

I think this is wrong ?..

But that's all my LaTeX!

CALCULATOR:

$${\mathtt{y}} = {\mathtt{8}}{\mathtt{\,\times\,}}\left({\frac{{\mathtt{2}}}{{\mathtt{4}}}}\right){\mathtt{\,-\,}}\left({\frac{{\frac{{{\mathtt{6}}}^{{\mathtt{3}}}}{{\mathtt{2}}}}}{{\mathtt{15}}}}\right) \Rightarrow {\mathtt{y}} = -{\mathtt{3.2}}$$

ooooohh.....Where did i go wrong...

Here is another one that you could have a go at finishing MathsGod1.  

It has a couple of new symbols for you too :)

the formula is

$$\\d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\
where\\
x_1=5,\quad x_2=3, \quad y_1=-2, \quad y_2=-6\\$$

you can plug the numbers in anon :)

CODING For MG    

\\d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\

where\\

x_1=5,\quad x_2=3, \quad y_1=-2, \quad y_2=-6\\

Well MG you can present the whole answer in LaTex

Good evening,     

Great answers today from Alan, CPhill, Rosala, Badinage, MathsGod1, Geno3141, Hawkeye and Will85237. Thank you 

Should i work it out in LaTeX?

Mon 4/5/15

FTJ means "For the Juniors"

Lots and lots of practice and make sure you understand all the basics :)

okay MathsGod1 here is a really handy thing to know

y=8* (\frac{2}{4}-\frac{\frac{6^3}{2}}{15})

$$y=8* (\frac{2}{4}-\frac{\frac{6^3}{2}}{15})$$

Lets look at what i have written here.

I would like the times sign to be a proper times sign   that is   \times

Also, the brackets are too little - i want them to be bigger   I do this with  \left(   .......   \right)

like this

y=8\times \left(\frac{2}{4}-\frac{\frac{6^3}{2}}{15}\right)

$$y=8\times \left(\frac{2}{4}-\frac{\frac{6^3}{2}}{15}\right)$$

Now, why don't you try to solve this and show all of your working.  

You will need to know that \div is a division sign.       :)

This might challenge your latex as well as your maths :)   You can check your answer with the forum calc :)

I would have to think really hard to even guess what you are asking  

You produce a lot more mathematics than LancelotLink does MG.  

He spends all his time monkeying around. 

Although now I guess he will be campaigning as well     ://

What else can i digest?     :)

I think you meant who the smallest.

1. $${\mathtt{1.52}}{\mathtt{\,-\,}}{\mathtt{0.7}} = {\frac{{\mathtt{41}}}{{\mathtt{50}}}} = {\mathtt{0.82}}$$
