    They have one of these in the Junior Cert boards so I thought we could do with one as well! The way it works is someone posts a question, then the next person answers the question and if they get it right they get to ask the next question (just include your question in the same post as your answer to prevent unnecessary 'correction' posts cluttering the thread)
    I will start with an easy one: in maths, define 'integer'.

    d1234 you are wrong. Root 2 and other surds cannot be expressed as fractions, yet clearly aren't integers. Try again.
