If the answer is 20, what is the question? Can you think of four possibilities using each operation- add, subtract, multiply and divide? Ask a parent to help you.

    1/2 of 40=20

    10+10=20
    100-80=20
    5*4=20
    40/2=20

    (Nellie remembered that doubling 20 gives 40, so dividing 40 in half gives 20 – you got there quicker than I did Nellie! Mummy)
