The term 'FOIL' is a mnemonic device in algebra used to remember the steps for multiplying two binomials: First, Outer, Inner, Last. It helps students systematically multiply the first terms in each binomial, then the outer terms, followed by the inner terms, and finally the last terms. This structured approach leads to an accurate product of the two binomials.

The 'FOIL' method was created as a teaching tool rather than being attributed to any specific individual. It aids students by breaking down complex multiplication processes into manageable parts: First (multiply first terms), Outer (multiply outermost terms), Inner (multiply innermost terms), and Last (multiply last terms). This method aims to reduce errors and provide a straightforward approach for multiplying binomials. Its simplicity makes it popular and effective in helping students understand algebraic concepts.

While 'FOIL' emphasizes order with its mnemonic structure, another method known as 'BOX' provides a visual alternative. The 'BOX' method involves drawing a box divided into four quadrants to organize and multiply binomial terms visually. Although both methods serve similar purposes—helping students with binomial multiplication—their primary difference lies in their visualization approaches: 'FOIL's systematic step-by-step guide versus 'BOX's spatial organization. Each has its advantage depending on whether students prefer mental frameworks or visual aids; however, FOIL’s ease of use makes it widely accessible and frequently employed in mathematics education.
