Calculators
A calculator is a hand-held inexpensive electronic device used to perform the operations of arithmetic. The simplest calculators can only do addition, subtraction, multiplication, and division, while scientific calculators can handle exponential operations, and trigonometric and logarithmic functions.

How do I calculate the square root of 32 divided by 2 without the use of a calculator?
sqrt(32)=sqrt(16 x 2) = sqrt(16) sqrt(2) = 4 sqrt(2)
Dividing 4 sqrt(2) by 2 , you get 2 sqrt(2) . This is the answer.
Display a pseudocode for a calculator program?
firstly try yourself then ask others or browse internet websites etc
How do you find the square root of 200 without a calculator?
Well, the easiest way is to note that √200 = √2 x √100 = 10√2. You can look up √2 in a book, and then just shift the decimal one place.
Alternatively, there is a procedure for computing the square root of a number with pencil and paper. It looks very much like old-fashioned "long division," but with some differences in the details.
- First, write the number you are finding the square root of, grouping the digits in pairs on either side of the decimal point. Thus, 200 becomes 2 00 . 00 00 00 00
- The first group of digits is just the number 2. Find the largest square that is less than that number. In this case, that's 1. The square root of 1 is also 1, and that is the first digit of the answer.
- Subtract the square from the previous step, leaving a remainder of 1, and bring down the next pair of digits, leaving you with 100.
- You now take the answer so far, double it, and put a blank next to it. In this case, that's 2_.
- Fill in the blank with the largest number that gives you a multiple 2_ * _ that is less than your working remainder. 21 * 1 = 21, 22 * 2 = 44, 23 * 3 = 69, 24 * 4 = 96, 25 * 5 = 125, so the largest multiple that fits our requirements is 24 * 4. Write the 4 as the next digit of the answer, and subtract 96 from the working remainder of 100, and bring down the next pair of digits.
- Repeat steps 4 and 5 until you reach the precision you require.
Here's what it looks like:
1 4 . 1 4 2 1 3 5 6 2 √ 2 00 . 00 00 00 00 00 00 00 00 1 * 1 = 1 - 1 1 00 24 * 4 = 96 - 96 4 00 281 * 1 = 281 - 2 81 1 19 00 2824 * 4 = 11296 - 1 12 96 6 04 00 28282 * 2 = 56564 - 5 65 64 38 36 00 282841 * 1 = 282841 - 28 28 41 10 07 59 00 2828423 * 3 = 8485269 - 8 48 52 69 1 59 06 31 00 28284265 * 5 = 141421325 - 1 41 42 13 25 17 64 17 75 00 282842706 * 6 = 1697056236 - 16 97 05 62 36 67 12 12 64 00 2828427122 * 2 = 5656854244 - 56 56 85 42 44 10 55 27 21 56

What calculator will find Square footage irregular shape?
I assume you mean the calculation required.
Split the irregular shape up into shapes for which you can find the area (eg rectangles, triangles), then the area of the shape is the sum of the areas of the smaller shapes.
How do you do a multiplication?
for example, 2x6=12
what you have to do is see the second digit, the 6, and look at the 1st digit, the 2,
which means you add six together 2 times
What symbol do you use for greater than and less than on a graphing calculator?
EDIT: Instead of doing what the person below said, you could hit [2nd] [MATH] and a screen comes up with the > and < and the ones with the line under it for greater/equal to and less/equal to
______________________________________________________________
You use the < and > symbols.
For ti 84, you go to 'Y=' . And then where it says 'Y1' and 'Y2' down the screen, go over to the left side and press 'enter'.
-For greater than, click it until you get a little black triangle pointing up
-For less than, click it until you get a little black triangle pointing down
For "greater than/ less than" symbols, on the TI-84 Plus: Hit "2nd", then "MATH" for the "TEST" menu. Should be right there.
What year was the first pocket calculator made?
I saw the first modern electronic pocket calculator in 1967 when I was attending engineering school at the University of California in Berkeley. It was made by Hewlett-Packard.
How do you calculate an antilog on a TI-86 calculator?
The anti-log is "10^x" listed above the "LOG" key on a TI-86 calculator. All you have to do to use it is press the yellow "2nd" key (this means shift) and then press the "LOG" key.
It all depends if your prepare baked or mashed potatoes for a dinner with family.
On the calculator what does the plus slash minus button do?
It changes the sign of your answer between positive and negative. For example, if your calculator says 50 and you press the +/- button, it will change to -50. Press it again and it changes back to 50. It is useful if you need to multiply several numbers together and then subtract them from another number. For example say you multiplied some numbers on your calculator and got 52.932646 and you need to subtract that from 100. Instead of clearing the calculator and typing 100 - 52.932646, you could just press the +/- button to get -52.932646 and then add 100, and you will get the correct answer. It saves a step.
Is there any games for the TI Nspire?
You can play Ti-84 games with the 84 keypad but I have yet to find games for the n-Spire CAS. So just download TI-84 games and use the 84 keypad.
It displays the power to which '10' would have to be raised in order to get the number you entered. That's the definition of the 'logarithm' or 'log' of a number. Examples: Enter 100. Hit 'log x'. Display '2', because 102 = 100. Enter 1000. Hit 'log x'. Display '3', because 103 = 1000. Enter 2. Hit 'log x'. Display '0.30103', because 100.30103 = 2. Enter 0.1. Hit 'log x'. Display ' -1 ', because 10-1= (1/101) = 0.1
When using the TI-83 or 84, you connect the wires that should come with the calculator. Then, you must press Second and the button down 1 and right 1 on both calculators. On the receiving calculator, press the right arrow key and then Enter. On the sending calculator, select the programs you want to send and press Enter.
How do you put notes into graphing calculator?
If you have a TI graphing calculator, you can install the NoteFolio app from Texas Instruments. It is located here:
http://education.ti.com/educationportal/sites/US/productDetail/us_notefolio_creator_software.html
You can transfer notes back and forth between your computer and your calculator. You can even create new notes on the calculator itself.
* 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.
How can you find the greatest common factor using a calculator?
Unless your calculator has a key for it, the only method I know is awkward. Example : Take 24 and 114. Divide 114 ÷ 24. It gives 4.75. Subtract the integer part (4) to keep only the fraction part (0.75). Remultiply by 24. This gives 18. Do the same thing with the smallest number 24, and the new number 18. Divide 24 ÷ 18. It gives 1.33333333. Subtract the integer part (1) to keep only the fraction part (0.3333333). Remultiply by 18. This gives 12. Do the same thing with the smallest number 18, and the new number 12. Divide 18 ÷ 12. It gives 1.5. Subtract the integer part (1) to keep only the fraction part (0.5). Remultiply by 12. This gives 6. Do the same thing with the smallest number 12, and the new number 6. Divide 12 ÷ 6. It gives 2.0. When there is no fraction part left, the game is over, and the smallest number found is the GCF. So the answer is 6. Another example with 17 and 35. Divide 35 ÷ 17. It gives 2.05882352941. Subtract the integer part (2) to keep only the fraction part (0.05882352941). Remultiply by 17. This gives 1. Start again with the smallest number 17, and the new number 1. Divide 17 ÷ 1. It gives 17.0. There is no fraction part left, so the answer is the smallest number found, which is 1. When two numbers have no common factors, the answer will always be 1, since you can divide anything by 1.
Where is the exponent key on a calculator?
It is the upwards arrow, it is the same symbol on the "6" key of your keyboard.
