It helps calculations if you think about compound interest as your money increasing every period (for instance, every year) by a certain factor. For example, if you get 5% interest per annum, your capital will increase by a factor of 1.05 every year. If you repeat this, say, 10 years, then your capital will obviously increase by a factor of 1.0510.
The detailed formula for the capital you have after a number of periods is thus:
(initial capital) x (1 + rate/100)periods
If you want to know only how much interest you earned, rather than the total money you'll have, just subtract the initial capital.

If compounded, interest = 81.244 and balance = 456.245 If not compounded, interest = 75 and balance = 450
Yes.
It is 0.833... recurring % if the interest is simple, or compounded annually. If compounded monthly, it is approx 0.797 %
It depends on the rate of interest, how it is compounded, and how long it draws interest.

Yes.
If it is not compounded the interest would be 2000x10x.05=1000 If it is compounded then it is different.

$194.25 if interest is compounded annually. A little more if compounded quarterly, monthly, or daily.
Yes: a year is not 50 weeks.
False. Interest upon interest is compounded interest
This gives total after n years: Principal x ((1 + interest rate) to the power n) eg 2500 @ 5% over 7 years compounded annually = 2500 x (1.05)7 = 2500 x 1.407 = 3517.75
In terms of economics, compounded interest means the interest earned from the principal and added interest. In many cases, this method is always used by some internet scammers to lure people to invest.
"Compounded annually" means that the interest is added once a year.
