I don't think it's right to call them all {aljebra}, so I try to come up with terms for them: 1. The basic meaning of "algebra" is manipulation of mekso. What's the word for "manipulate"? 2. Abstract algebra, in one sense, is the study of sujgri, piljygri, and dilcygri. So girzu saske. But what's the word for "operation"? (The other sense is algebra, in the first sense, in fields other than Q, R, or C. For instance, one can compute an elliptic curve sum by taking the formal derivative of a polynomial in a finite field and get sensible results, even though taking a derivative of a function in a finite field makes no sense.) 3. An algebra is a vector space with multiplication. {farlaili'i piljygri}? 4. An algebraic number is a number which is a solution to a polynomial equation. Any more suggestions? phma
