Conversion of Tree Diagrams into Numerical Expressions
Conversion
of Tree Diagrams into Numerical Expressions
For instance, consider the tree
We could first find 
as 10, then 
as 5
when we multiply the results 10 and 5 we get 50.
When the nodes for addition and subtraction are interchanged the value remains the
same which is represented using tree diagram as given below.
Does it mean that the branches also can be interchanged
? Yes, when the node is addition it is possible.
But it is not possible when the node represents
subtraction.
Therefore from this tree diagram.
The expression can be converted into either (10−5)
× (8 + 2) or (8 + 2) × (10 − 5) or (2 + 8) × (10 − 5) or (10 − 5) × (2 + 8) without
changing the value.
