(1): "^-15" was replaced by "^(-15)".

Step  1  :

 1.1     10 = 2•5

(10)^-15 = (2•5)^(-15) = (2)^(-15) • (5)^(-15)

Equation at the end of step  1  :

  0 -  (3 • ((2)(-15)•(5)(-15)))

Step  2  :

Equation at the end of step  2  :

           3    
  0 -  —————————
       (215•515) 

Step  3  :

Final result :

      -3                                       
  ————————— = -3.00000 • 10-15 
  (215•515)
