My calculator fell down,and it didn't seem to have any scratch but d top 2 screw at the back began to shake and weren't stable anymore,so i tried turning it ON bt it didn't turn on,when i opened the back piece i noticed that the battery was all alone with nothing attached to it,and i don't knw what next to do.

I would contact Casio customer service to see if it can be repaired and if it is still under warranty.

I do not understand why places sell the 991ES for more than $20.00 cost of the fx-115ES Plus which clearly has more functions and features!
Can someone _please_ explain that makes 991ES so darn special? Compare the number of functions on the Face (keyboard) of the 115ES Plus,
and a 991ES/Plus... I ask you: which would you think is cheaper? and which would be for more advanced users?

Thanks!

This is a looooooooong shot, but here I go.

The 115 is a North America model, while the 991 is an international model. I'd guess they are importing the 991, therefore have to pay import tax on it, hence the higher price.
