Finally I decided to purchase a Casio FX-991EX even though I already got the FX-300ES I have been using this 300ES a lot when study math stuff this calculator price is very cheap compare to it features and functions. Until yesterday I buy another one but now the 991EX because of many positive reviews. This one is a little more expensive than 300ES when I got it but the features and functions is much more and computation speed is very fast. The photos attached gave the comparison look and noticed the inside slide cover of the 300ES came with the basic instructions.
