Binomial calculator headache !

Hi guys,

Im studying for my stats exam and working out binomial problems. My maths is poor, do I'm finding hard enough understanding the theory without my calculator causing headaches! I am using a scientific HP10s and when I try to work out say 0.10 to the power of 3 which is x but my calculator is giving me a weird 3.6x10 to the power of -03 answer instead of the whole answer o.0036. Can someone please let me know if I'm not using the calculator properly as u have triple checked my formula and used a differed calculator which gave me the answer.

Thank you for your help in advance , I have exams next week !

Your calculator is set to scientific mode. Re-write the calculator's result

$\displaystyle 3.6 \cdot 10^{-3} = 3.6 \cdot \frac1{1000} = 0.0036$
