I enter the following in sage:
361-4*-216 #sage comment: I would like sqrt this without copying & pasting
I'd like to then obtain the sqrt of that answer after its been generated.
On the Ti-83 plus, the device was able to generate 'Ans' after I pressed an arithmetic symbol such as division.
If you're in a notebook environment and type 361-4-216 into a cell and get the answer then in the cell underneath you would refer to the previous calculation using the _ symbol. So typing sqrt(_) will give you the square root of the calculation in the previous cell. I find it's easiest to assign calculations to variables, eg a=361-4-216, after which you can use the variable in other calculation easily.
This also works in the command-line version; the underscore holds the result of the last returned computation.
