Foil stands for
first
Inner
outer
last

if you had (a+b)(c+d) you would get this by foiling:

Ac+bc+ad+bd

a and c are the first nubers in eac h parenthisese,
b and c are the two numbers in the center
a and d are the two numers on the outside
b and d are last numbers in each parenthisese.
The samne goes for equations for more parenthisese.  Hope this helps, and let me know if you need anything else!
