:: Sure, it's a wiki. But why not first check (and discuss) the intentions? You may be right about using the ℝ (From where did you get the non-TeX ℝ? (Is it safe on all browsers?)) and perhaps even using "real" does not hurt though elementary arithmetics only uses rational numbers.

More elementary?
Paul, it is a good idea to have a non-formal article on arithmetic. What do you think about making it even more elementary? (The more formal treatment can be left to the articles on rational and real numbers, etc.) Most, if not all, mathematicel jargon could be avoided. Take e.g.:
"Two (or more) numbers can be added (denoted by +), and the result is again a number. This addition does not depend on the order in which it is performed. For example, 3 + 5 ≡ 5 + 3 (= 8)."
It is not necessary to use "binary", "commutative", "field". Even "real number" can be replaced by "number".
