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]
For binomial multiplication, distribution is sometimes referred to as the FOIL Method [2] (First terms , Outer , Inner , and Last ) such as: (+) (+) = + + +. In all semirings , including the complex numbers , the quaternions , polynomials , and matrices , multiplication distributes over addition: u ( v + w ) = u v + u w , ( u + v ) w = u w + v ...
The term "FOIL rule" is rarely used, "FOIL method" is an order of magnitude more common. I suggest moving the article accordingly. -- Vaughan Pratt ( talk ) 19:04, 6 September 2009 (UTC) [ reply ]
In mathematics, the polynomial method is an algebraic approach to combinatorics problems that involves capturing some combinatorial structure using polynomials and proceeding to argue about their algebraic properties. Recently, the polynomial method has led to the development of remarkably simple solutions to several long-standing open problems ...
In arbitrary-precision arithmetic, it is common to use long multiplication with the base set to 2 w, where w is the number of bits in a word, for multiplying relatively small numbers. To multiply two numbers with n digits using this method, one needs about n 2 operations.
Amid growing anxieties surrounding reported drone sightings, the FBI has issued a warning against a new trend of pointing lasers at aircrafts.
For example, a child who has a profound deficiency in growth hormone (especially if they are a cancer survivor with damage to the pituitary gland) may need to continue taking HGH as an adult ...
The Aggies (7-2, 5-1, SEC) entered the game as just 2.5-point favorites and started Marcel Reed at QB. Reed took over for Conner Weigman in A&M’s Week 9 win over LSU and the Aggies scored TDs on ...
