Hi Jason
thanks for this ( I did mean 'c' not 'y'; apologies).
I didn't know about QQbar().
Why does QQbar(c) return what appears to be a numerical result, with a
question mark after it?
That is an approximation of the exact number (the question mark

Hi. I am having difficulty using sage to manipulate square roots.
Consider:
a = 1 + sqrt(2) + sqrt(3)
b= (a^2).expand()
c = sqrt(b)
Then 'y' should be equal to 'a'.
I get:
sage: a = 1 + sqrt(2) + sqrt(3)
sage: b= (a^2)

Hi. I am having difficulty using sage to manipulate square roots.
Consider:
a = 1 + sqrt(2) + sqrt(3)
b= (a^2).expand()
c = sqrt(b)
Then 'y' should be equal to 'a'.
But, given 'y' I cannot make sage return the simple form.
Trying
y.simplify_full()
doesn't do

Hi, I am trying to implement the infinite polynomial ring as a free
commutative algebra.
I am unsure of exactly how to do this. So far I have:

And starting with sage-4.7.1.alpha4 you can also do
sage: timeit('2**128', seconds=True)
