Expanding the FOIL method
Most of us learned the FOIL method as a way to multiply algebraic expressions. FOIL stands for First, Outer, Inner, and Last, which is how we multiply the terms.
(X + 2)(X — 3) = X² -3X + 2X -6 = X² -X -6
However, we can expand the use from algebra to things like multiplying mixed numbers and decimals too. Let’s look at an example.
