Objective:
 
To learn about the verbal statement and algebraic statements.
  
Verbal statement and Algebraic statements:
   
Do you know the difference between the verbal statement and algebraic statements?
 
Let's see an example to understand this clearly.
Example:
Arun is twice taller than Kumar. That is Arun height is two times larger than Kumar's height. Now, this is known as a verbal statement.
 
If you write the above verbal statement in an algebraic statement we get,
 
Let the height of the Kumar is \(x\).
 
Therefore Arun height \(=\) 2×HeightofKumar=2×x=2x.
 
In the above example, we understood that normally we use the verbal statement to mention any mathematical operation, then we translate this verbal statement to an algebraic statement to find the unknown value.
Now let's see a few examples of how we are using the verbal and algebraic statement in the mathematical operation.
 
[Note: In a verbal statement the unknown value \(x\) is represented as some number or a number].
