What is an expression tree? How an expression is evaluated using an expression tree?

Algebraic expressions is as given here
a/b+(c-d)e
That has an inherent tree-like structure. For illustration following figure is a representation of the expression of above equation. This type of tree is termed as an expression tree.

The terminal nodes or leaves of an expression tree are the constants or variables in the expression (a, b, c, d, and e). Therefore the non-terminal nodes of an expression tree are the operators (+, -, ÷, and ×).
