Algebraic argument and proof

By the end you’ll be able to

• Represent even, odd and consecutive integers and multiples algebraically ($2n$, $2n + 1$, $n$, $n + 1$)
• Construct algebraic proofs of number facts, e.g. prove that the difference between the squares of two consecutive odd numbers is a multiple of 8 (Higher)
• Disprove a statement with a counterexample and explain why an argument is invalid
