$$\\\\\mbox{Write\;it\;down\;like\;this.}\\\\-16\0^2+0^2+160$$

Now, do the exponents.

$${\mathtt{\,-\,}}\left({{\mathtt{16}}}^{{\mathtt{2}}}\right) = -{\mathtt{256}}$$

$${{\mathtt{0}}}^{{\mathtt{2}}} = {\mathtt{0}}$$

Now add

$${\mathtt{\,-\,}}{\mathtt{256}}{\mathtt{\,\small\textbf+\,}}{\mathtt{160}} = -{\mathtt{96}}$$

So, $$-{\mathtt{96}}$$ Is your answer.

Australians call mathematics maths.  So an Australian knows what maths is.

You call mathematics math.   So some of your friends may not know that maths is the same thing. 

Ratios and fractions have a lot in common.  so you deal with them very similarly.

a:b = c:x

$$\\\frac{a}{b}=\frac{c}{x}\\\\
\frac{b}{a}=\frac{x}{c}\qquad \mbox{Here i turned both sides upside down}\\\\
\frac{x}{c}=\frac{b}{a}\qquad \mbox{Here i swapped sides}\\\\
x=\frac{bc}{a}\qquad \mbox{Here I mult both sides by c}\\\\$$

Does that help Dragon?

Can I solve it? In order to solve it, I need to know what to multiply.

Just multiply them together.

YOu can use the calc on the home page.

Let's substitute x into 8

x=8

now change everything into fractions

now, I don't get it. It has to be 2 4/8, bit 4/8. Can someone please help?

Can you explain this deeply Melody?

Say what??

No if it was a serious question it means he was not from Australia.  

O, the anonymous user is from Australia!

In the US people shorten mathematics to math

In Australia we shorten it to maths 

 inverse sin is the same as arc sine

Use asin

$$\\\frac{a}{b}=\frac{c}{x}\\\\
\frac{b}{a}=\frac{x}{c}\\\\
\frac{x}{c}=\frac{b}{a}\\\\
x=\frac{bc}{a}\\\\$$

A mi me sirve.

Ejemplo:

a number is missing from the following list: 3, 5, -2, -4, x. (the missing value is x.) the mean of the list is -2. what is the value of x?

So we have

(3 + 5 + -2 + -4 + x)/5 = -2      multiply both sides by 5

3 + 5 + -2 + -4 + x  =  -10        simplify

2 + x   = -10                             subtract 2 from each side

x = -12

Maths is mathematics. 

The answer to life, huh?... Well the answer is simple and not simple. It is to enjoy, have fun, and to love everyone until you go to heaven...

Ope you ask questions, cause I am one level up!

$$\mbox{radius of the moon = 1 737.4 kilometers}$$

$$\sqrt\frac{4}{9}=\frac{2}{3}=0.6666666666666666$$

 To achieve that goal, you must go to college, and take an awesome job, like an astronaut, and you'll be an ultimate swagger...

[(5 * x - 1) * 2 ] / 5 = 3     simplify

[(5x - 1 ) * 2] / 5  = 3    

(10x - 2) / 5  = 3       multiply by 5 on both sides

10x - 2  = 15             add 2 to both sides

10x = 17                   divide by 10 on both sides

x = 17/10

This mathematical expression (or equation, or whatever it is!) can not be solved on the best calculator in the world... Only human brains can solve it... Like CPhill's brain...

I know! When I saw it at first glance, I came to check the answer, and then I saw it correct, and it was a magnificent answer! 

Wish everyone good grades...
