thanks for the reply, I have just done it all again and the scientific calculator is giving me my origional answer,but a standard calculator give me your answers? lost
If you have a scientific calculator:
fraction button -> 11 +- square root 97 -> down button -> 2
Natural display calculators mean you don't need the brackets on the calculator.
If you need more help just PM me here and it'll give me an email.
