What are "Imperial minims"?

I just looked them up

Yes I know.

The search function doesn't work very well yet.  There are still a number of issues that Andre Massow has to work through.  

Many features do work well.  Andre is working hard and he site is constantly being improved but it will take time.  Sorry.

I have no great advise for your learning/study techniques.  Even if I had a technique that suited me well (which I don't) it still probably would not work for you. Everyone learns differently.   

We can't answer that - If we don't know the (future) question how can we know the (future) answer?

Yes, I figured that!     

I think that is about the ugliest emicon wink that i have ever seen!

Look here.

Shouldn't it be in a liquid measure Chris?

Look at this thread.

I'll give you an example.

0.045

there are 3 numbers after the decimal point so there will be a 1 followed by 3 zeros on the bottom.  That is 1000

45 goes on the top. so we have   $$\frac{45}{1000}$$  This can be simplified by dividing both the top and the bottom by 5 so

$$\frac{45}{1000}=\frac{9}{200}$$     

Does that help?

$$9.1\times 10^{-2}$$

alright, the power is -2 

so you have to move the decimal point 2 places. The negative sign means that you have to move it in the correct direction so that the answer gets smaller.

so you jump the point over the 9 and then over the invisable 0 and you get  $$.091$$     I think it is a good idea to put a zero in front of the decimal point so that it is easier to read so I would leave the answer as 

$$0.091$$     

Does that all make sense.
