How to solve prefix expression
WebMay 8, 2005 · Expressions in prefix are solved by scanning the equation for an operator with two immediate values to the right of it. This is continued and repeated until there are no more operators left. Graphing prefix expressions follow a simple algorithm, which is as follows: Write operator. Go left unless the node is an immediate value.
