Yep...that's what I mean. By the way, how do you produce the mathematical sign on Windows for pi? I await your reply with patience.

Would you explain to me just - step by step -  how I convert Si(3pie) into a decimal?
   Thank you.

Onward and upward.

Thanks, bobbym. I got there in the end, so it was  down to my stupid errors.

I'm working my way through some probability questions but, despite employing the correct approach, I'm falling at the last hurdle. Please show me how 13/15 x 0.5 x 0.5 x O.5 x 0.5 + 2/15 x 0.3 x 0.3 x 0.3 x 0.3 becomes 5.52%.
   I just can't arrive at that result.

As an elderly gentleman who has decided to encourage his 'little grey cells' to become more active, I have joined your happy band in the hope of having a good workout. Currently I'm using the 'Khan Academy' site to help blow away the cobwebs but will doubtless be postings queries soon.
  Much power to your elbows.
