```   the numbers are:  10 9 480 644 2217 36 144 26 2 32 6 16 9 15

A = sqrt(480 + sqrt(16)) = sqrt(484) = 22
B = sqrt(644 + 32) = sqrt(676) = 26
C = sqrt(2217 - 6 - 2) = sqrt(2209) = 47

the numbers become:  10  9  36  144  26  9  15  A=22  B=26  C=47

D =  B + 15 - sqrt(C - A) = 26 + 15 - sqrt(47 - 22) = 36
E = 26 - 10 = 16

the numbers become:  9  36  144  9  D=36  E=16
...apply square roots...
the numbers become:  3  6   12   3    6    4

the math is:  (12 / 6) * 3 - (6 / 3) = 4

more math is:  6 + (12 / 4)! - 3 - 3 = 6

all sixes math:  3! = 6 = 12/sqrt(4) = 3! = 6
sqrt(sqrt(6 * 6 * 6 * 6)) = 6

putting it all together...

the numbers are:  10 9 480 644 2217 36 144 26 2 32 6 16 9 15

the math is:  sqrt(144) / sqrt(15 + sqrt(644 + 32) -
sqrt(sqrt(2217 - 6 - 2) -
sqrt(480 + sqrt(16))))
* sqrt(9) - (sqrt(36) / sqrt(9)) = sqrt(26 - 10)
