| Jul 3, 2013 at 3:16 | comment | added | Martin | Introduction to Modern Algebra is on a precalculus level and does not introduce fields and rings formally. The distributive law (for numbers) is formulated on page 30 in the usual way (at this point Kelley is assuming that addition and multiplication are associative, commutative and unital). | |
