I am never quite sure that I have understood what the figures mean. I tend to skip over the graphs or charts that I come across, hoping that I can get the information I need from the text.

I wouldn't say I have learnt a great deal more since school and regret not having a better grounding in it. When faced with a problem I feel confident if the problem is within the realms of my capability. However, I do know that I end up going the long way round. Or as we say in Guernsey, I go round Sark to get to Herm (two islands off Guernsey). I am constantly worried about the use of maths – I always presume that I will get simple problems wrong if numbers are involved. We were mixed-ability taught in all subjects in the first year, but after that we were rigidly grouped according to ability and, as expected, I ended up in one of the lower maths groups, where I remained for the rest of my time at secondary school. Any chance of improving my mathematical skills were also limited by the school deciding we were a lost cause, and being taught by a procession of some of the most eccentric and disinterested teachers I have ever met.

On reflection I suspect that I have spent most of my working life sidestepping anything vaguely connected with maths and have consequently developed a number of avoidance techniques. These range from ‘I am busy at the moment, I am not sure what you want to know, try to work it out yourself’, through to ‘I haven't got my glasses’ – all very similar to the techniques employed by those who have difficulty in reading. If I see a pure mathematics problem then I don't attempt it. I tend not to be drawn to articles in newspapers/TV that have a mathematical focus. I was good at hiding within the class… I usually stay quiet and I would never contemplate a job where I would have to add up in front of others. I am not terribly confident when presented with certain sets of figures, but, if I work through it carefully, I can usually cope with it.

I have just started a science course, so I know I will need to improve my skills. I am aware that presumed difficulties with maths prevent me from attempting certain aspects of the course. Basic skills could help my confidence, though I feel it may be too late to start. (Arts student.) In my previous course, I was studying German. My ideas about what mathematics meant to me were not even considered and did not develop throughout. My next course (Third World Development) will be different, but I haven't started it yet.

1, 1, 2, 5, 8, 10, 12, 15, 24 | This set of nine values is arranged in ascending order and the median is 8. |

32, 25, 20, 16, 14, 11, 9, 9, 4, 0 | This set of 10 values is arranged in descending order and here the median is (14 + 11) + 2, which is 12.5. |

One specialist I spoke to reckons that the rate could rise to over 50% within the next 20 years. A quick look at the graph suggests he could be right.
