What is a Mathematical statement?

Mathematical statment
- A mathematical statement is a statement that can be judged to be true or false
 Ex: The sky is green
   - since this statement has no truth value , it is a false mathematical statement
   -   The sky is blue 
   - Since this statement does have a truth value , it is a true mathematical statement
Negations
- they always have the opposite truth value of the original statement
- both statement need to be true to have truth value
Ex:
 Original statement : The sky is blue 
Negations: The sky is not blue

Conjunction

Ex: 
Original statement: The sky is blue , the clouds are white
