Use brackets in appropriate place to the expression 3 × 8 - 5 which gives 19 and convert it into tree diagram for it.

Given expression is 3 × 8 - 5 . Here, we observe that 3 × 8 = 24 and 24 - 5 = 19 . So, the terms in the expression are ( 3 × 8 ) and 5 . ( 3 × 8 ) - 5 is obtained by subtracting 5 from ( 3 × 8 ) . Therefore, numerical expression is ( 3 × 8 ) - 5 . Hence, the tree diagram for the expression is given below:

Convert into a Tree diagram ( 9 × 5 ) + ( 10 × 12 )

Given expression: ( 9 × 5 ) + ( 10 × 12 ) We know that, Tree diagram are a general way of representing arithmetical expressions. It is a picture which look like an upside-down tree. Every node has one or two branches. And the leaves are numbers. The branching nodes have operations on them. Hence, required tree diagram is shown below.

Convert into a Tree diagram ( 10 × 9 ) - ( 8 × 2 ) + 3

Given expression: ( 10 × 9 ) - ( 8 × 2 ) + 3 We know that, Tree diagram are a general way of representing arithmetical expressions. It is a picture which look like an upside-down tree. Every node has one or two branches. And the leaves are numbers. The branching nodes have operations on them. Hence, required tree diagram is shown below.
