 Mathematical Reasoning


Negating a statement means menyangkal or menidakkan a statement.
Example
Statement: If x = 2, then x3 is equal to 8.
Negating the statement will be: If x = 2, then x3 is not equal to 8. 
The truth value of the statement will change if we negate it. In the above example, it changes from true to false.


For a statement "If p, then q", its converse will be: "If q, then p".
Example:
If x = 2, then x3= 8.
The converse of the above statement is:
"If x3= 8, then x = 2."
