I can tell you Queen Guinivere of Camalot the evil plan of Sir CPhill!

True story, word by word.

$$-{\mathtt{1}}$$ is the answer.

Hope it helps!

Well, that's the way of life.

The name says everything.

I thought I was the guy that slayed dragons in Camalot to save you guys!

Dragon. You are the pesky little boy. You are well liked in Camelot but you will need to grow up considerably before you can become a squire.  

$$Answer: 77$$

Do you want to know how to solve it?

First, do the parentheses.

$$\left({\mathtt{7}}{\mathtt{\,\small\textbf+\,}}{\mathtt{3}}\right) = {\mathtt{10}}$$

$$\left({\mathtt{5}}{\mathtt{\,-\,}}{\mathtt{11}}\right) = -{\mathtt{6}}$$

$$\left({\mathtt{18}}{\mathtt{\,\times\,}}{\mathtt{0}}\right) = {\mathtt{0}}$$

Now, multiply.

$${\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{10}} = {\mathtt{100}}$$

$${\mathtt{7}}{\mathtt{\,\times\,}}{\mathtt{0}}{\mathtt{\,\times\,}}-{\mathtt{6}} = {\mathtt{0}}{\mathtt{\,\times\,}}-{\mathtt{6}} = {\mathtt{0}}$$

Now add.

$${\mathtt{100}}{\mathtt{\,\small\textbf+\,}}{\mathtt{0}} = {\mathtt{100}}$$

Now, subtract.

$${\mathtt{100}}{\mathtt{\,-\,}}{\mathtt{23}} = {\mathtt{77}}$$

So, $${\mathtt{77}}$$ is the answer.

Hope it helps!

Thanks, guys!

I now understand absolute values!

Thanks!

Yup, you wouldn't make #2 negative, because the absolute values make everthing inside them positive if they are negative. If they are positive already though, you just leave them positive.

So #2's answer is 3/2, as Aziz said.

So, the answer is $$\frac{3}{2}$$?

Okay. Thanks Melody!

How do use \\\? I really don't understand that part.

Thanks for the points, btw!

Question #2 should be positive as Ninja stated: Absolute values make everything inside them positive.

Question 1) $${\mathtt{4}}$$

Question 2) $${\mathtt{\,-\,}}{\frac{{\mathtt{3}}}{{\mathtt{2}}}}$$?

Question 3) $$-{\mathtt{1.7}}$$?

Are they correct NinjaDevo? OR---

Is this correct anybody?

1. |-4| --> taking abs. value means you obtain the positive part --> 4.

2. $$|\frac{3}{2}|$$ = $$\mathbf{\frac{3}{2}}$$.

3. -|1.7| = -(1.7) = -1.7.

Absolute values make everything inside them positive.

For example, |-7| = 7.

But, they only make things inside them positive. So, if you had -|7|, it would become -(7), then -7.

See if you can use this info. to anwer those three questions of yours. :)

5*2*(7+3)+7*0*(5-11)-23-(18*0)

Remember: pemdas [parentheses, exponents, multiplication, division, addition, & subtraction]

We must first evaluate the parentheses -->

5*2*(10)+7*0*(-6)-23-(0)

Next, we must perform multiplication -->

10*10+7*0-23 --> 100+7*0-23 --> 100 + 0 - 23 -->

Note that we had to do multiplication first so it is not 107*0-23.

Finally, we can just add and subtract to obtain our final answer -->

100 + 0 - 23 = 100 - 23 = 77.

And who am I from Camalot?????

I have no secret plan. I can tell YOU GUYS the PLAN THAT CPHILL HAS!!!!!!!!!

Thanks, Stu.

I don't know of what plan you are talking about. 

And Melody, Don't you yanks know anthing!?!?!

Oh!!!

Thanks, Melody, I forgot. Thanks for the reminder!

Sorry heureka!

It is just a specific model of Xerox [a company that makes photocopiers/printers/etc.]

Like: Lenovo G655 or Dell XPS or HP Deskjet 3910.

Please provide the question.

Let's see here. We have three options.

A. The equation has a variable on both sides.

B. The equation is true for any value of x.

C. The equation is not true for any value of x.

A would not be true, because you can still solve for x even if there is x (a variable) on both sides.

Think about it, if you had something like 5x+3=2x-9, you could still solve for x. This equation has a variable on both sides.

B would not be true, and we could prove that by putting a couple values of x into the equation. Let's try 4 and 15.

$$\begin{array}{rll}
4x+5&=&4x-1\\
4(4)+5&=&4(4)-1\\
16+5&=&16-1\\
21&\neq&15
\end{array}
\boxed{21&\neq&15}\\

\begin{array}{rll}
4x+5&=&4x-1\\
4(15)+5&=&4(15)-1\\
60+5&=&60-1\\
65&\neq&59
\end{array}
\boxed{65\neq59}$$

Finally, we can just prove our answer is C by putting in values for x.

Nomatter which value you put in for x, there will never be a solution for x.

$$\begin{array}{l}
\left(-\frac{5}{6}\right) + \left(-\frac{8}{9}\right)\\
The\;problem\;here\;is\;that\;we\;need\;a\;common\;denominator.\\
To\;fix\;this,\;let's\;multiply\;the\;first\;fraction\;by\;\frac{3}{3}\;
and\;the\;second\;fraction\;by\;\frac{2}{2}.\\
This\;will\;give\;us\;a\;common\;demoninator\;(bottom\;number)\;of\;18.\\
\left(\frac{-5}{6}\times\frac{3}{3}\right) + \left(\frac{-8}{9}\times\frac{2}{2}\right)\\
\left(\frac{-15}{18}\right) + \left(\frac{-16}{18}\right)\\
Now\;that\;we\;have\;a\;common\;demoninator,\;we\;can\;add\;these\;fractions.\\
\left(\frac{-31}{18}\right)\\
So,\;that's\;our\;answer.\;You\;could\;also\;write\;this\;as\;a\;mixed\;number\;like\;so:\\
-1\frac{13}{18}\\
\end{array}$$

Yeah im starting to hate you melody jr............

Using the calculator on the home page here you can enter x then press the ^y√x key then type 4 and hit the enter key. 

Or enter x then press the square root key (√x) twice.   

You want the difference between 1/2 and 1/5.  To find this express each fraction in terms of a common denominator.  Here 10 is the least common denominator and 1/2 = 5/10 and 1/5 = 2/10, so the difference is 5/10 - 2/10 = 3/10. So she has to finish 3/10 by Friday.
