What is a conjecture?

Back

A conjecture is a statement that is believed to be true based on observations but has not yet been proven.

Front

How can you prove a conjecture is false?

Back

You can prove a conjecture is false by providing a counterexample.

Front

What is a counterexample?

Back

A counterexample is an example that disproves a conjecture or statement.

Front

If x^2 = 4, what is a counterexample to the conjecture that x = 2?

Back

x = -2 is a counterexample to the conjecture.

What is the difference between inductive reasoning and deductive reasoning?

Back

Inductive reasoning involves making generalizations based on specific observations, while deductive reasoning involves drawing specific conclusions from general principles.

Front

What is the importance of counterexamples in mathematics?

Back

Counterexamples are important because they help to test the validity of conjectures and statements.

Front

Can a conjecture be proven true?

Back

A conjecture can be proven true through a formal proof or by showing that it holds for all cases.
