Sorry I never got a mail when you asked the question, I guess you've solved it by now...

any for anyone else who may have the same problem..you have fix selected(significant figures)

press the mode button top right, repeatedly until it displays Fix sci norm,
press the number underneath Fix which is probably 1
then press the number of decimal places you would like Between 0 to 9 yours at the moment is obviously set to 0

Sorry for being so late....

Hello,

Sorry to disappoint you but you cannot do it due to the fact that the representation of irrational (SQRT(2), ..) and transcendental (e, pi, etc.) numbers on a calculator or even a computer is approximative : a number like sqrt(2) has an infinite number of decimal digits while the number of internal digits a calculator uses to store results is limited (10, 12, 15 or even 24).
Once an irrational or a transcendental number has been evaluated numerically it generally ceases to be exact.

If you want to manipulate algebraic expressions, you need a calculator that has a CAS (computer algebra system) operating system and a symbolic algebra option.

Some exemples of calculators with a CAS are The TI nspire CAS, the HP 48 series, HP 49, HP 50, Casio ClassPad3xx, the TI 89titatium, the TI Voyager 200PLT, the TI 92 and Ti 92Plus. The ones with a fullblown keyboard might not be accepted on certain standardized test.

You may also try to get some emulators on the Internet for the HPs or the TI 8xx and play with them on the computer.

Hope that helps.

Hello,
Since you bent on deactivating the very features that make your calculator so versatile and so powerful, here it is.
Press [SHIFT][MODE][2:LineIO] and you will see no more fractions, nor radicals etc. You asked for it.
Hope it helps.

Testimonial: "I bought the calculator because it was on sale and I like Casio calculators; not for its fractional abilities. I can easily switch it back now. Thanks"
