Th"e [EXP]" button your talking about is the "x(white box_superscript)" next to the x-squared and underneath the navigation button.

No there IS NO "[EXP]" BUTTON on the Casio FX-300ES Scientific Calculator.
AND the supposed replacement for it "10^x" button is NOT equivilent.
Just try to calculate 4.18844x10^-4 / 2.324423x10^-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:
(4.18844x10^-4)/(2.324423x10^-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.
