You shouldnt answer questions like that. Tell the people they should be able to calculate that themselves, cause they should. If they really are not, tell them how to multiply rational numbers in general and maybe do some even easier exercises with them, and they should be able answer it.

Thanks. I'm still trying to figure how you did that though...

Pi consists of an infinite sequence of digits, there's no such thing as a last digit.

Well, its $$0.6666$$ repeating. $$3 \cdot 2 = 6$$, wow.

But i personaly wouldnt advice you to write the numbers ugly like this. Rather:

$$3 \cdot 0.2222\dots = 3 \cdot \frac{2}{9} = \frac{2}{3}$$

They are equivalent.

$$\frac{A-P}{P} = \frac{A}{P} - \frac{P}{P} = \frac{A}{P} - 1$$

By the way, these answers are not only equivalent to each other, but also right answers to the question asked.

im a $$\pi\mathrm{zombie}$$

Its a way to express $$100 \cdot 100$$ in words

For any number $$x$$, $$x$$ cubed means $$x^3$$ or $$x \cdot x \cdot x$$. So $$14$$ cubed is $$14 \cdot 14 \cdot 14$$.

If you need it as a decimal value, just use any calculator, or you might even just multiply it yourself. I would advice you not to though, i dont think there is a nicer way to express this number than $$2^3 \cdot 7^3$$.

He is that number that you said. I'm not going to type the number its not long. 

Sorry have a correcting problem 

• Sorry
• my
• commas

also for those who don't know what AKA means and Lol. AKA means also known as. Lol means laugh out loud

First you should know there is not only one inverse to the cosine, it's not injectiv.

That said you are probably looking for arcuscosine, short acos in the calculator, the one most commenly used. Pressed the '2nd' button in the top left, and the 'acos' button which should now appear there cos was before

not sure if that's really a square but I tried my best

If you enter a single number it should be automaticly presented in that way.

Now if you want to have the result of a calculation in "sientific notion" enter it, and press '=' twice, once to get the result and once to make it be prsented in the way you want.

$$23+\frac{8}{25} = 23 + \frac{32}{100} = 23.32$$

$$\frac{n}{2}-12$$

21 duh u tupid

(17 − 13) + 33 × 4

(4)+132=136

136

believe it and i have like 7 more problems like this. my math teacher is crazy.

Pi, denoted by the symbol π, is the sixteenth letter in the Greek alphabet. Mathematically, it is derived from a circle's circumference divided by the diameter. It is a real, irrational number, meaning that it is infinite. Here is some of pi: 3.14159265358979323846264338... That's as much as I've memorized. 

2c -6c = 7

-4c = 7

c = -4/7

no square needed

23/5= 4 with three left over so its 4 3/5
