NEITHER Dr. Hilbert nor the reviewer make any suggestion that the commutative law of addition is best proved as a deduction from the laws of multiplication. But the laws of multiplication are so often ...

Students are introduced to Professor Arbegla and her amazing machine. They suggest numbers (and later geometric shapes) to go into the machine, and then analyze what comes out. Students learn to look ...

Students write multiplication equations based on groups of objects using zero and one. In this lesson, students write multiplication equations based on groups of objects using zero and one. Mrs.

The object of the paper is to give a lattice generalization of Krull's ideal theory of commutative rings without finiteness assumptions, which in particular includes rings, distributive lattices and ...
