Transcript Numeracy Across the Curriculum

Numeracy Across the Curriculum
Bistromathics itself is simply a revolutionary new
way of understanding the behaviour of numbers.
Just as Einstein observed that space was not an
absolute but depended on the observer's
movement in space, and that time was not an
absolute, but depended on the observer's
movement in time, so it is now realized that
numbers are not absolute, but depend on the
observer's movement in restaurants.
Adams, Douglas Life, the Universe and
Everything.

I am ill at these numbers.
William Shakespeare, (1564-1616) Hamlet.
I'm sorry to say that the subject I most
disliked was mathematics. I have thought
about it. I think the reason was that
mathematics leaves no room for argument.
If you made a mistake, that was all there
was to it.
Malcom X
The National Numeracy Strategy has
ensured that pupils arrive at secondary
school with secure number skills.
Secondary maths departments effectively
develop these skills so that they are fluently
applied in all secondary subject studies.
Olley, C.J. (1961-) A Statement
A good calculator does not need artificial
aids.
Lao Tze (604-531 B.C.) Tao Te Ching
I remember once going to see him when he
was lying ill at Putney. I had ridden in taxi
cab number 1729 and remarked that the
number seemed to me rather a dull one, and
that I hoped it was not an unfavourable
omen. "No," he replied, "it is a very
interesting number; it is the smallest
number expressible as the sum of two cubes
in two different ways.“
Hardy, Godfrey H. (1877-1947)
Ramanujan, London: Cambridge University
Press, 1940.
