### What is Meant by Foil?

In Maths, the term FOIL stands for First, Outer, Inner, Last. It is a technique to distribute the binomials. Here, first means multiply the first terms which occur in the binomial. Outer means multiply the outermost terms in the product. Then inner represents multiplying the inner terms of the binomial. Finally, last means multiply the last term in the binomial. Once the process is completed, then simplify the algebraic expression.
For example, (x+1) and (x+2) are the two binomials
By using FOIL method, it becomes
(x+1) (x+2) = (x. x) + (x.2) + (1.x) + (1.2)
