Calculator Two for One
Sharp doubles the potential of its EL-9900 scientific graphing calculator by equipping it with a unique two-sided keypad that has a simple side for basic operations and a complex side for advanced algebra and statistics. To change the calculator’s keypad, just remove it, flip it over and snap it back in place. The EL-9900 a powerful device with 827 built-in mathematical functions, 132-by-64 dot screen and 64KB of memory yet it weighs less than 9 ounces and sells for under $100.
I want to know the differences between these two calculators and which one is best for me (7th grade currently, advanced student, taking 8th grade Algebra right now.)

I think EL-9900 is best because it is programming calculator.
