SOURCE: i cannot find where the greater than, smaller

On Casio calculators, inequality grap?ing has always been part of the OS. To perform inequality graphs, press the graph icon.
Press the F3 key to open the TYPE tab at the bottom of screen.
Use the F6 key to access other choices.The relational operators are then displayed and you can select the one you want to create the inequality function.

The casio manual is rather comprehensive and I am surprised that you could not find an answer to your questions. Did you leaf through it?

SOURCE: How do I type an equal sign into the calculator?

Look at the top left corner of the keypad. If you have a = sign marked on the f ace of the calculator (near a CALc or Solve key) you can enter the = by pressing [ALPHA] then the key next to which there is an = sign.
If you do not have that second = sign, you cannot enter it.
The FX-115ES and the FX-991ES do have that sign to allow the user to enter equations. In your calculator you only have three calculational modes: the general COMP mode, the STAT mode and the Table Mode. No equation mode. Sorry.

How to put in an "equal sign " into the TI-30XS Multiview calculator?


Yes you can enter basic or complicated expressions, you just can't enter equalities nor equations. The calculator cannot solve equations. When an expression (without an = sign) is entered, pressing the ENTER key will evaluate it.

The equal sign is in fact a command to tell the calculator to start calculating. It cannot be used independently, out of this context. Newer scientific calculators that have equation solving capabilities may have a second equal sign used to write equations.
See if you have an additional = accessed by pressing an ALPHA key first.

How do you use the equal sign on the ti-84


The equal sign of the TI83/84/Plus is a relational operator like less than , greater than, less than or equal to) You use it when you are testing if two values (numbers, expressions, or matrices) are equal.
For example, if in one your programs what you do at a certain time depends on the equality of two expressions, you test the equality by a statement :
If A=B do this action.

How do i use the equal sign when solving an equation?


You enter the problem into the calculator and when you are finished you press the equals sign to make it give you the answer to your problem.

Here is an example;

If I wanted to know what the sum (or total) was for 2 + 10+ 16 - I would enter the number 2 and then the plus sign + and then the number ten and the plus sign + and then the number sixteen and the plus sign again + and then press the equals sign which looks like this =. when I press the equals sign = the calculator gives me the answer to my question of what the total of those numbers are.

I hope this helps?

How do you type an equal sign on the TI 84 calculator


On these units, the "equals" sign ([=]) is located in the [TEST] menu. This menu is a [2nd] function of the [MATH] key.

This function is used to test if two expressions are equals. To evaluate an expression, simply hit [ENTER].

Good luck.
