Kaepernicks

can you provide a example?

I would say it's about  $${\mathtt{2.986\: \!431\: \!478\: \!97}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{1}}}$$

It would be $12.

Found on the calculator on the main 

It's about:

  $${{\mathtt{3}}}^{-{\mathtt{1.9}}} = \left({\frac{{\mathtt{1}}}{{{\mathtt{3}}}^{{\mathtt{1.9}}}}}\right) = {\mathtt{0.124\: \!013\: \!686}}$$

For volume:

  $${\mathtt{V}} = {\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{r}}}^{{\mathtt{2}}}{\mathtt{\,\times\,}}{\mathtt{h}}$$

For surface area:

$${\mathtt{A}} = {\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{\pi}}{\mathtt{\,\times\,}}{\mathtt{r}}{\mathtt{\,\times\,}}{\mathtt{h}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{r}}}^{{\mathtt{2}}}$$

For lateral surface:

$${\mathtt{L}} = {\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{\pi}}{\mathtt{\,\times\,}}{\mathtt{r}}{\mathtt{\,\times\,}}{\mathtt{h}}$$

1) don't ask on a math forum.

2) that's it

$${\frac{{\mathtt{1}}}{{\mathtt{5}}}} = {\mathtt{0.2}}$$

Simply divide 1 by 5, then multiply by 100

$${\mathtt{0.2}}{\mathtt{\,\times\,}}{\mathtt{100}} = {\mathtt{20}}\%$$

Makes more sense now...I wasn't sure what "16 from" meant

$${\sqrt{{\mathtt{600}}}} = {\mathtt{24.494\: \!897\: \!427\: \!8}}$$

Other than that I'm not sure what you mean...

I was wrong...

$${\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{\,-\,}}\left({\frac{{\mathtt{3}}}{{\mathtt{7}}}}\right) = {\mathtt{\,-\,}}{\frac{{\mathtt{9}}}{{\mathtt{7}}}}$$

Very simple. Multiply 3 by -3 in the numerator to get -9. this works for any multiplication with fractions

$${\frac{{\mathtt{1}}}{{\mathtt{5}}}}{\mathtt{\,\times\,}}{\mathtt{200}} = {\frac{{\mathtt{40}}{\mathtt{\,\times\,}}{\mathtt{1}}}{{\mathtt{2}}}} = {\frac{{\mathtt{20}}{\mathtt{\,\times\,}}{\mathtt{1}}}{{\mathtt{4}}}} = {\mathtt{5}}$$

I hope I did that right...

Yes, thank you ^_^

I'll try to help you the best I can, but I need a question first

A little derpy, not going to lie, but:

I couldnt figure out how to put the exponents in the square like that, so I just drew them on 

Yes. A negative exponent will flip the number with the exponent to the denominator.

Basically: $${{\mathtt{8}}}^{-{\mathtt{1}}} = {\frac{{\mathtt{1}}}{{\mathtt{8}}}}$$  

Another example would be:  $${{\mathtt{13}}}^{-{\mathtt{32}}} = {\frac{{\mathtt{1}}}{{{\mathtt{13}}}^{{\mathtt{32}}}}}$$

From there it's simple math with exponents to solve it.
