Is it more profitable to receive $2000 now or $3500 in 10 years? Assume that money can earn 6% interest compounded monthly.
I would take the 2000 right now and invest it at the 6% compounded monthly.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.
