statement	negation?
i am in physics class.	○	○
i am not in history class.	○	○
i am in algebra class.	○	○
it is not the case that i am in algebra class.	○	○

Explanation:

• The original statement is "I am not in physics class". The negation of a statement "not \(p\)" is \(p\). So the negation should be "I am in physics class".
• For the statement "I am not in history class", it is about history class, not related to the negation of the original physics - class statement.
• For the statement "I am in algebra class", it is about algebra class, not related to the negation of the original physics - class statement.
• For the statement "It is not the case that I am in algebra class", it is about algebra class, not related to the negation of the original physics - class statement.

Answer:
