I do not understand your question Mellie  

I do not understand this question, :?

You have asked this question about a thousand times today !

I don't understand what is being asked but maybe someone else will.  :/

Great work anon

$$(4\div 0.4)\div 0.4 +4=29$$

That number has 12 zeros - so it is  10^12

the square root is 10^6

9/2=4.5

5*4.5=22.5 cups of water.

Hi anika,

I am here everyday mainly for answering questions and I have an account :)

I would be interested how other people use this forum too :)

yes

$$log_{10}15 =\frac{log_x15}{log_x10}$$

x can be any positive number except for 1

$$\\150n=180(n-2)\\
150n=180n-360\\
360=30n\\
n=360/30\\
n=12 sides\\$$
