Logic Mathematic

Today we learn about the logic
before learning about the logic we have to know the statement. The statement contains a sentence that is false or true, or not worth the two. The statement can be said to be true when in accordance with actual circumstances.



Consider the following sentence
1. 5 + 7 = 15
2. 5 is a real number
3. 2 is an odd number



Well the statement is false or true can be, now and then note the following statement:
1. What is your name?
2. When was your birthday?



Now the question is not really worth and not worth one.
in logic there is an open sentence that is a sentence that has a variable and can be completed
For example y + 2 = 3
Then it can be solved y = - 2 + 3

y = 1
