To calculate e.........they begin with 2 ^x...............and split it...........how could u split the square root of 2?.........................ignoring the decimals.............1/2 the square root of two............two of those...............one half of something............+ one half of that same something added up.........is one whole of that same something...................which is the same as the square root of 2.........over 2..


started. With 1 split we have 2¹ or 2 times as much. With 4 splits we have 2⁴ = 16 times as much. As a general formula:

Said another way, doubling is 100% growth. We can rewrite our formula like this:

It’s the same equation, but we separate 2 into what it really is: the original value (1) plus 100%. Clever, eh?
Of course, we can substitute any number (50%, 25%, 200%) for 100% and get the growth formula for that new rate. So the general formula for x periods of return is:

This just means we use our rate of return, (1 + return), “x” times.
