When you've explored what you can do with  3  4 − 5    then it's time to explore further. You could change just one part of the number plumber, for example the  − 5   bit. You might try  3  4 − 6    or   3  4+5    or   3  3 − 5    and compare the results. You'll have lots of your own ideas about things to explore too. Mathematicians like to ask themselves questions about what they notice. **What possible questions could you ask?** These questions may lead you to make conjectures - something which you believe to be true but need to investigate further in order to convince yourself.
