Sep 04, 2007 by Amanda | Posted in Homework Help

How would I belittle delete a mixed fraction on my graphing calculator. For example 4 1/2. Like for a scientific calculator its down-to-earth to spot it because its the abc button, but i can't find it on the TI-89 calculator

try lately using 4 + (1/2)

Which Scientific Calculator(s) Has/have Same(similar) Key Sequences as TI 89?

I've been looking. Casio has some attractive possibilities. But, I don't want to get used to key sequences for higher math functions on a calculator that won't fool around over to the one I'll eventually need to use for the SAT & beyond. I'm just talking about getting through Advanced Algebra with it. I'm hoping people who be told Algebraic function key sequences will answer. Do geeks use Yahoo? Should I try another forum? Thanx :)

Is there a scientific calculator that can factor or supports an Application with factoring capabilities?

I suck at factoring and our schoolmistress will allow any scientific calculator. I have a TI-89 but she wont let me use it because its graphing but all i need is the factoring column!

Im desperate! I don't care if its Texas Instruments, Casio, Canon, HP, ANYTHING! please support! =]

Try to use casio 991ES. I currently using this calculator. It can fact cubic and quadratic function completely. It will give you the roots, and the establish are offcourse the factor. For higher degree equation like quintic and quartic, 991ES is still benevolent by using its EQN function. But in this case it can only give one factor. At least it help you find one agent and you may now simplify the function into cubic and quartic.
