This worksheet builds on the work done in Algebraic Proof (A) by using the basic concepts of writing expressions for even numbers, odd numbers, consecutive numbers etc. and asking for more complicated sums, differences and squares to prove statements such as "Prove that the difference between the squares of any two consecutive numbers is always an odd number" and "Prove that the sum of three consecutive numbers is always a multiple of 3".
More algebraic proof questions can be found in Algebraic Proof (C).
