  • "Thanks for some great resources which stimulate lots of ideas.
    Could you produce a calculator activity that includes the use of brackets, powers, squaring etc to encourage students to make use of functions on a scientific calculator?"

  • "A good resource but it is a shame it doesn't obey the rules of BIDMAS. Having spent a long time talking about BIDMAS in previous weeks the solution 5 x 5 - 4 x 4 was offered for 9. Unfortunately the calculator gave 64.
    It did provoke a discussion but I allowed the answer 9!"

  • "A great idea but ruined for me by not following the BiDMAS rules. It thus allows incorrect answers and confuses pupils who get the right answer (e.g a student doing 55 - 4x5 - 4x5 for 15 and seeing an "answer" of over a thousand!)."

  • "Agree with the other comments. A good exercise, only spoiled by the calculator not knowing BODMAS!"
