Original Message (ID '129572') By yehuda:
Slot notation is simple #1 (or just #) is the first argument to a function #2 is the second argument ... & just says that the expression is a function so Function[{x,y},x+y] Function[#1+#2] and #1+#2& are all the same The first one uses explicit (dummy) names The last two use # notation. The last one is a shortcut for the second one As for Root, just use N to get numerical values Since you didn't mention how you got your result (which function generated it) I cannot comment further
