Calculators

You enter your number in the calculator then you times it by the percent and then press the percent button. Hope this helps!

If you don't have a calculator with a percentage sign divide the amount by the total and multiply by 100. For example:

In a test I got 18/20 or 18 out of 20.

I then go:

18 divided by 20=0.9

After this go:

0.9 multiplied by 100=90%

Hope this makes sense I've tried to explain it in a simple way. If you need further help just message me on my message board. <this part is Juralique by the way

scientific calculators have scientific calculations such as scientific notation, but mechanical ones dont.

The shape of a pie is circular. If its diameter is d units, the area is 0.25*pi*d^2 square units.

Solar power, ie, the sun.

This will depend on the type of calculator you have. This will depend on the type of calculator you have.

D. enter the number; press the square root key

Here are the steps:

1. Find the square root button, it usually located at the middle.

2. Press the square root button.

3. Insert a number.

4. Press '='.

5. You get the answer.

P.S. These steps belongs to scientific calculator.

SketchAndCalc, added to related links below.

Performing such a calculation manually is indeed complex and time consuming.

SketchAndCalc is an online Perimeter and Area calculator that allows the user to draw any regular or irregular shape with their cursor. The area and perimeter results are displayed when the shape is closed. The scale can be adjusted to accommodate very large areas such as the floor plan of a building, or the square meters area of a kitchen work surface or smaller.

Using your cursor, draw the shape of any object. Line lengths are displayed below each line to ensure measurements are true. And they can be adjusted after the shape is complete. The area and perimeter results are then displayed. It has been compiled as an Adobe Flash component so the user may need to install the Adobe Flash browser plug-in.

In addition, the tool offers a Sharing feature which allows the user to save the calculation as an URL to paste into an email or blog, and allow users to collaborate on the drawing as many times as they wish.

This tool is currently free to use.

You press pi button on the calculator or type in 3.14 you then times it by the radius then square it. :) x

The Einstein Calculator is a calculator made by Albert Einstein. I have no clue what its about. Probably a normal calculator. I see u chase d! Desiree s. :)

Texas Instruments graphing calculators are really easy to use and there are a lot of applications and programs available for the TI graphing calculator platforms (TI-83+ family, TI-84+, TI-Nspire, and TI-89 family). Thus, you will be able to easily find a program for your specific class (Calculus, physics, chemistry, etc.) at Texas Instruments app store and also open source program repositories like ticalc.org.

The TI calculators also are the most commonly used in the more advanced mathematics courses, including Calculus I,II,III, differential equations, etc. because they have all of the features and functions one would need in a easy to use, user-friendly interface.

* Also, if you are interested, you can download a software package for your TI graphing calculator to help you improve your score on the SAT test at www.calc-tech.com . It's called the SAT Operating System (SAT_OS) and can be used during the actual test to reduce time on math problems and improve the accuracy of your calculations.

Assuming you have a scientific calculator which has a square root button ([√]) the method depends upon which calculator you have, and in what mode the calculator is set.

The most recent Casio calculators have two modes of entry: MathIO and LineIO. InMathIO the sequence is:

[√] [<expression>] [=]

In LineIO, if the <expression> is more than one number brackets needs to be entered:

[√] [(] [<expression>] [)] [=]

This LineIO type of entry is used on the older Casio calculators. With older models of Casio calculators, and other manufacturers the functions work on the displayed value which is replaced by the value if the function. With these calculators, the expression is entered first and then the square root key is pressed:

[(] [<expression> [)] [√]

parentheses are only needed if the square root is of an expression.

Examples:

Square root of 16

MathIO: [√] [1] [6] [=]

LineIO: [√] [1] [6] [=]

Other: [1] [6] [√]

Using Pythagoras to find the hypotenuse of a right angle triangle with sides 3 and 4:

MathIO: [√] [3] [x²] [+] [4] [x²] [=]

LineIO: [√] [(] [3] [x²] [+] [4] [x²] [)] [=]

Other:[(] [3] [x²] [+] [4] [x²] [)] [√]

With MathIO the square root symbol extends over the expression as each key is pressed which is why the parentheses are not needed in the last example.

You can type letters from A-F, X, Y and M by pressing alpha.

That topic is covered, exhaustively, in detail, with examples,

in the instruction booklet that comes with each of the many

different models of scientific calculator .

Youy can use a TI 84.

The square root of 55 will be roughly halfway between 7 and 8.

7.5 is too high.

7.4162 works for me.

This is for a Statistics class and I need help on how to operate step by step this calculator.

Use this to help you out:

http://support.casio.com/pdf/004/fx_plus_ch_intro.pdf

Just ctrl+f what stats function you want, for example variable (when doing variable testing).

Two ways.

Easy way first. Simply push the S-D button. This will toggle fractions and decimals.

More permanent way:

SHIFT

SETUP (also the MODE button)

2 (Select option 2 Line 10)

That's it!

When you want to go back to fractions then:

SHIFT

SETUP

1 (Selection option 1 Mth 10)

Now your back in fraction mode.

The first pager was invented in 1962 by Ma Bell and was a radio paging system. Pagers were popular in the 1980's and 1990's.
