Algebraic Structures: Mathematical frameworks—such as lattices, algebras, and varieties—employed to model logical connectives and inferential relations. Admissible Rules: Inference rules that ...

The rule "1 through 9 each appear exactly once in the top row" can be captured with some sneaky pieces of algebraic thinking. The sum of the top row is going to add up to 45, which is to say x₁ ...

They contend that the state board adopted the new rules illegally. Their underlying concern is that the algebra policy is unworkable and unfunded. The new study, released today by the Brookings ...

He argues that many of the rules of algebra could have been otherwise. The adopted ones came about by a variety of factors, and don’t necessarily offer the best resource for dealing with every ...

A new policy in California requires students to be enrolled in an algebra class by the 8th grade, according to the LA Times. Unfortunately, the rule, which goes into effect in 2011, is largely ...
