Calculator help for algebra 1

Do you know what mode i should have it in for algebra 1? Is it compex mode? I cannot figure out how to enter equations and stuff. Not even this ^ can I find. Your help is appreciated. I have a final tomorrow, but am very unfamilar w/ the calculator.

Cryshug24 the mode(s) you want to use is mth IO and line IO for algebra. push the shift mode then #1. to write out a long equation push shift mode #2. you have to keep playing between the two modes to get the correct answer.

Polynomial equations


This calculator cannot do algebra so it does not handle polynomials. It does not have an EQN (equation) solving mode so you cannot enter an expression set = 0 and solve it for an unknown variable X.
It does have a table Mode where you can enter an expression y= F(X) and generate a table of values. If in the expression F(x) a numerical coefficient is a fraction just enter it as a fraction, possibly enclosed in parentheses. If it is a decimal number just enter it as a decimal number. Converting it to a fraction is not going to generate any more precision in the result. You lose precision when you go from fraction to decimal, but you do not make a number more precise by converting it from a decimal representation to a fraction.

How we can multiply two algebraic equation in 991 ES CASIO calculators


The Calculator does not have a Computer Algebra System (CAS), and cannot perform algebraic operations with variables. However if you enter some expression with variables, it can solve for one unknown after it prompts you for the values of the others

How would i solve for an expression and be able to leave it in terms of the variable, like (2a-1)(8a-5) and get the answer with the variable in it


This calculator cannot manipulate algebraic expressions. You can enter an expression and generate a table of values. You can enter an equation in one unknown and solve it. But you cannot do algebra.
You would need a calculator that has a Computer Algebra System (Algebra FX 2.0, or ClassPad 300/330). Sorry.

Algebra


Yes it can be keyed in.
To enter the X, use the ALPHA followed by ). To enter the = sign, you use [ALPHA][CALC].
To use the calculator to SOLVE an equation you must enter the equation, then press [SHIFT][CALC] to (SOLVE). You will be prompted to solve for X. Follow it from there.

As to the case you show, the constant terms will drop and you are left with 26X=0, and the solution is X=0.

Note: The calculator cannot do algebra with letter symbols. It does not have a Computer Algebra System or CAS.

How do I input an = sign into an algebraic equation using an elw535


There is no need to enter an = sign in an algebraic equation because the EL-W535 does not handle them. It has only 3 modes : The computational mode, a statistics mode and drill mode (to learn or practice operation tables). Thus any press of the = sign will execute the command you typed. If you just entered an expression, the = sign will have it evaluated using the current values of the variables you used. If you have not stored anything in a variable, the calculator will use 0.
You can use the 4 D keys to store a function key for example SINH^-1. You cannot even store in them an elaborate formula, just a function key or a shifted function key.
Sorry for the limitations of the calculator. To have more functions you should look for the EL-W516.

My calculator is always in the scientific mode, i want it to be in normal mode, how?


Hi nolski,
Have a nice day.
Listed below are the ways to set your calculator from scientific to normal mode. 1.Clear your calculator of the last equation you did by pressing the "Clear" button. 2.Click the "Mode" button and use the arrow keys to scroll over "Normal" mode. This will set the calculator up to do basic equations versus any long algebraic equations, or other types of equations on which your were previously working. 3.Practice setting the mode to normal when your are done using your calculator so you always know what mode the calculator will be on when you turn it on next time.
