# Foil Method - Simple Proof and Quick Alternative Method

in MES Science3 months ago (edited)

You probably have used the foil method in Elementary and High-school math class but you may not know quite why it works. Well the proof is quite simple and it involves just considering the multiplication as an Area of a rectangle. Also in the video, I show a very quick method to foil out very complex equations and it involves creating a simple table and is very easy to memorize. If you don't know the foil method inside and out, then this video is a must watch since you'll have to use the foil method in almost every math, engineering, physics class.
