Nice work on these informative videos, very helpful. I must purchase a new calculator, as my current one is Verboten for Post Secondary in Canada. I've narrowed it down to 2 Casio models: FX115ES, and Fx991EX. The price is roughly the same here. Are the extra functions on the old 115 as important as some say? Thanks.
