### What is factoring and give the examples

Quick-Start Guide When you enter an expression into the calculator, the calculator will simplify the expression by expanding multiplication and combining like terms. At this point the calculator will attempt to factor the expression by dividing a G C F, and identifying a difference between two squares, or factorable trinomials. Use the following rules to enter expressions into the calculator. Variables Any lowercase letter may be used as a variable. Exponents Exponents are supported on variables using the ^ (caret) symbol. For example, to express x 2, enter x ^ 2. Note: exponents must be positive integers, no negatives, decimals, or variables. Exponents may not currently be placed on numbers, brackets, or parentheses. Parentheses and Brackets Parentheses ( ) and brackets [ ] may be used to group terms as in a standard expression. Multiplication, Addition, and Subtraction For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is optional when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * ( x + 5 ) can also be entered as 2 ( x + 5 ) ; 2 x * ( 5 ) can be entered as 2 x ( 5 ). The * is also optional when multiplying parentheses, example: ( x + 1 ) ( x - 1 ). Order of Operations The calculator follows the standard order of operations taught by most algebra books - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. The only exception is that division is not currently supported; attempts to use the / symbol will result in an error. Division, Square Root, Radi cals, Fractions Division, square root, radi cals, and fractions are not supported at this time. A future release will add this functionality.

that's all I can say basically I learned it this way.

### How do I find the square root of a number? and how do I enter scientific equations?

For square roots, use the square root key just to the left of the divide key. For example, 4 square-root = will give you 2.

The calculator doesn't have any way to store equations, scientific or otherwise. If you mean scientific notation, use the EE key just above the 7 key to enter exponents. For example, to enter 1.23x10^6, press 1 . 2 3 EE 6. For negative exponents, make sure to use the +- key to the right of the decimal point instead of the - key.

### Want to know how to calculate a number raised to a power

Use the general power key marked with X to the y ( look for the image of a key on same line as Power in the screen capture)
You enter a number then press the power key and finally the exponent. If exponent is complicated (fraction, negative or other) enclose the exponent in parentheses.

You aslo have dedicated keys for certain powers and roots (square, square rooot, cube, cubic root)

### How to work a casio fx115es calculator

To clear the display, press the AC button. To enter powers press the power key, labeled x with a raised small solid square. To use it enter the number: if the screen displays x with a dark square enter the exponent in the raised square. If the display shows a ^, enter exponent after the caret ^. Close any parentheses by entering the matching right parenthesis.

### How to use the exponent key on a casio fx 300ES calculator ?

The key to use for the square, and the cube are well marked and they share the same physical key (X to 2) or [SHIFT][X to 2]. Similarly the keys to use for the square root and the cube root share the same physical location (the square root key, to the right of the square key).

For any other exponent, including fractions and negative exponents you use the universal power key labeled [X to ] ( X with a raised square).
1. You enter the base (the number to be raised to a power).
2. You press the [X to ] power key.
3. You close the parenthesis (the right one).
4. You press [=]
Sometimes the result may not be displayed as a decimal number, but as a radical (if you take a root). To make sure it is displayed as a decimal number, in step 4 above, press [SHIFT][=]

### What do i key in for 2 to power of 12??

Hello,
Between the x`squared key and the log key there is a key with an x with a raised small figure of a solid square. That is the key you use to enter arbitrary exponents.
1. If calculator is in MathIO ( a Math indicator appears on the upper band of the screen), enter the base of the power (here 2). A number 2 with a raised empty square appears.The cursor will blink in the raised square. Enter there the exponent (here 12) and press [=]. Result 4096 appears at the bottom of the screen.
2. If in LineIO (no Math indicator appears on the narrow band at the top of the screen), press 2 and then the key I talked about above. On the screen a number 2 appears with a hat and a left parenthesis. Type in the exponent (here 12) , the right parenthesis and press [=]. The calculator should display 4096.000...
Hope it helps

### How to enter exponents

Hello,
You use the key on the 6th line of the picture. You enter the number, press the key then enter the exponent. At the end press =

If you want to extract roots other that square and cubic, you use the same key, but the exponent will be 1/4 , 1/5, 1/6.
Hope it helps.
