Why Use Expression Trees?

They provide a clear structure for evaluation.

Source Expression

((3+4)*5) - (6/(1+1))

Key Advantages

1. Natural Precedence

The tree's structure naturally enforces the correct order of operations. Operations deeper in the tree must be evaluated first.

2. No Parentheses Needed

Once the tree is built, parentheses are redundant. The parent-child relationships define the grouping of operations.
