I actually tried to answer this several times, but unfortunately the forum grue seemed to eat my answers, ---- that and I've just obtained a new laptop so am going through all the general setup shenanigans when the default rubbish and security kicks in.
It's actually an xp machine (one of the last made), which my brother got 6 months ago and has never used. Sine he now wants a netbook (for the reason that he has never used his laptop), and I wanted an xp laptop things worked out very well.
Anyhow, now that I'm on my pc I can give answers to this.
Actually Aprone Pitermach was dead right for me too.
Even at secondary school when i was doing all lessons on a laptop (one reason I now am quite happy with carrying a laptop around with me), the one exception was maths, which I stil used a perkins brailler for.
Sinse then though i've just not needed that facility, Funnily enough, even when i did A-level biology and psychology which certainly did! take some use of statistics and such, I was able to cope on computer sinse most of the calculations required tended to be bog standard percentages and the like.
Even now I don't really have the need to perform long division, though I do stil occasionally find myself performing long multiplication or percentage based somes occasionally, ---- for instance when playing a game like Core exiles and wanting to calculate how much fuel my ship gets in a day or my prophits for selling x units of a resource at x creddits per unit.
Because my ability with spacial logic is always so bad (worse than most other people whether blind or not), I actually found maths a very uneven subject.
When dealing with algebra, basic equation balancing or the like I always got on well, but as soon as graphical (ie, use of graphs), or columnized representation came into it I found things far harder because of my issue with space.
For me, it was always easy to simply do things in my head than sit and try to plot a graph, construct a pie chart or the like.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
