1. No there IS NO [EXP] or [EE] BUTTON on the Casio FX-300ES Scientific Calculator.
   AND the supposed replacement for it “10^x” button is NOT equivilent.
   Just try to calculate 4.18844×10^-4 / 2.324423×10^-5 = and see what answer you get, IT WILL NOT BE CORRECT!
   This would be correct if the calculator had a proper [EXP] button, which represent inherently x10^x.
   4.18844[EXP]-4 / 2.34423[EXP]-5 will give the correct answer, IF this calculator only had that button.
   To get the correct answer using this calculator you will have to input it like this:
   (4.18844×10^-4)/(2.324423×10^-5) =
   This is amazing and outrageous, considering this is supposed to be scientific calculator, you cannot even enter numbers naturally in scientific notation, you have use parenthesis and tricks and double check to make sure they are all there, or you will get the wrong answer.

2. I really like this calculator. I am a teacher and I have one. This calculator enables me to quickly calculate fractions. I like the calculator so much that I bought my 8th grade algebra students one(10) as a graduation gift.

3. This calculator was a replacement for my old Casio that finally died after 15 years! It’s great but I had trouble setting up the regular calculator mode. It does come set up in scientific mode. So make sure you read the instructions before starting use.

4. My first scientific calculator was a Sharp. Then I spent many moons in the land of TI. I’m so fond of the TI-84+ I had firmly decided I was a TI-gal. Then, I tried to buy some for my classroom a night or two before the start of the school year and the store was out of TIs. They had this lovely calculator. I’m embarrassed to admit just how long I stayed in front of that display debating over whether I was willing to commit to an unknown brand, especially when I didn’t care for the Casios I had seen before. Finally, desperate to have a few on hand for my students, I purchased them.

   It didn’t take long for my students to find all the neat features. I originally chose them for the permutation/combination features and was curious about how useful stacked fractions would be for high school students. WOW.

   My only complaint (until recently) was that they are so fabulous, five of mine walked off. This was bad news…until…I discovered the next level up which includes imaginary/complex numbers. So for next year…I’m going to upgrade my stash and guard them more fiercely.

   I only put four stars because I soooo want those complex numbers now and all the other features I’m thinking I can get. I still prefer a TI-84, but our students are not allowed to use graphing calculators on their end-of-course test so I want them to get comfortable with a calculator that will serve them well. I was wishing I could put 4.9 stars (or 49/10 stars as my calculator would say). This is really a wonderful little device.

5. My son is completely satisfied with this for use in his first Algebra class. I bought this due to good experience with Casio calculators and the good price. I bought myself one in my 2nd year of college to use in Accounting – EL533 is the model, I think. I still use it. Purchased in 1985 and still works like a charm 24 years later. Can’t beat that!
