'It's like plaiting fog'

摘要

I wasn't a great mathematician at school but I managed. I got a 'B'. When I became an undergraduate in psychology, again I managed. Day to day I know when I am late, I know when I have a limited time on a task, I can count my daily calorie intake (when I can be bothered) and I can lighten my purse by counting out all the change just so I don't have to break into a 10 pound note. I also know approximately how much is in my bank account at any given time. In essence, I take seeing and understanding number for granted. And I use the skill every day.
