The FOIL method is a special case of a more general method for multiplying algebraic expressions using the distributive law. The word FOIL was originally intended solely as a mnemonic for high-school students learning algebra. The term appears in William Betz's 1929 text Algebra for Today, where he states: [2]
[1] [2] When n = 2, it is easy to see why this is incorrect: (x + y) 2 can be correctly computed as x 2 + 2xy + y 2 using distributivity (commonly known by students in the United States as the FOIL method). For larger positive integer values of n, the correct result is given by the binomial theorem.
The process of the reverse Jigsaw method can be explained in 3 steps: Students gather in mixed groups where they are each given a case study with a number of questions or one complex question to discuss. Each group member is given a unique topic, so a discussion is initiated within it, and the main points and outcomes are noted.

This method was frowned upon by my high school math teacher by the fact that it can cause confusion and errors when answer expression with positive/negative numbers. ie. (x + 3)(x - 7) = the answer could be incorrect by the confusion of the minus sign. I think there should be some articles that explains the negative aspect of this rule.
Don Quixote and his sidekick Sancho Panza, as illustrated by Gustave Doré: the characters' contrasting qualities [1] are reflected here even in their physical appearances. In any narrative, a foil is a character who contrasts with another character, typically, a character who contrasts with the protagonist, in order to better highlight or differentiate certain qualities of the protagonist.
Events are listed whether they took place in the line of duty or not, and regardless of reason or method. The listing documents the occurrence of a death, making no implications regarding wrongdoing or justification on the part of the person killed or officer involved. Killings are arranged by date of the incident that caused death.
The FOIL algorithm is as follows: Input List of examples and predicate to be learned Output A set of first-order Horn clauses FOIL(Pred, Pos, Neg) Let Pos be the positive examples Let Pred be the predicate to be learned Until Pos is empty do: Let Neg be the negative examples Set Body to empty Call LearnClauseBody Add Pred ← Body to the rule
