PRC declared that using 991ES and 991ES PLUS Casio calculators are prohibited.
As I enter college from algebra 1 to Engineering economy I always use 991ES PLUS as my weapon in every exam. My day to day life depend on it from budgeting to liquidations of my expenses. I try to explore the different modes and keys of my calculator in order to formulate shortcuts in solving problems but right now the news is heart breaking and I lost 1/8 of my confidence.
Keep on fighting!
Remember! what you become right now is what you strive before.
THANK YOU
