Question about Texas Instruments TI-83 Plus Calculator

Press MODE then select "NORMAL" on the first line. Optionally, you can select the desired number of digits after the decimal point on the second line.

Be aware that if the magnitude of the result is too large or too small then the calculator will automatically switch to scientific notation no matter what settings you have.

SOURCE: scientific notation when not wanted.

Unfortunately, you don't. For numbers whose magnitudes differ too greatly from 1, the calculator automatically switches to scientific (or engineering) notation. You can press MODE and change the display settings, but there is no setting that will force the calculator to show this number without an exponent.

SOURCE: use negative exponent in scientific notation

Use the (-) key in the far left column to enter the negative sign. Not just for exponents, either, but for any negative value.

SOURCE: How would you do negative

Use the (-) key for negative numbers (not just exponents) instead of the - key. The - is to subtract one value from another, (-) is to input a negative value.

SOURCE: How do you use negative

4 y^x +/- 3

The y^x key is just above the divide key, the +/- key is just to the right of the decimal point key.

Of course it is possible!

There seem to be many ways to do this on this calculator.

Assuming we cannot do scientific notation, we can always do

6.02 x 10 ^ 23 / 3.01 x 10 ^23. However, we have to put brackets in to get BEDMAS to work correctly!

6.02 x 10^23 / (3.01 x 10^23) - for the 10^23, type 10 then the y to the x key and then 23.

Using the scientific notation, we can type in 6.02 EXP 23 / 3.01 EXP 23.

Good luck with your chemistry test tomorrow!

Take care,

Paul

Hi there,

Type in your base and then press the button that says y with an x as an exponent (last row of the small buttons, second from the left). and then type in your exponent.

You can write it in different manners. But there are two special ways scientific notation and engineering notation.

**Scientific Notation** (d stands for digit, any digit), D is any digit except 0

D.dddd....d*10^(exponent) . The first digit, before the decimal mark is 1,2,3,4,5,6, 7,8 or 9

You case

567346.=5.67346*10^5

**Engineering notation**

The exponent must be a multiple (positive or negative of 3)

Your case

567,346=0.567346*10^(6). The first digit can be 0.

The number of decimal digits retained depends on the number of so-called significant digits.

Engineering notation ALWAYS puts the exponent as a multiple of three (kilo, mega, giga, etc). If you want the exponent as it is, use scientific notation. You can put the fx-115EX into scientific notation by pressing SHIFT MODE 7 and then entering the number of digits you want after the radix mark. Unfortunately there is no way to have the calculator adjust both the mantissa and exponent by anything other than three.

Look for a key that is marked EE, or Exp, or x10^x. To enter a number in
scientific notation, you enter the decimal part, then press the Enter
Exponent key, followed by the exponent. If exponent is negative, you
precede it with a press of the change sign key (-).

Once a number is entered there is no special treatment: multiply it divide, or add it.

The "problem" is not how to calculate with numbers expressed in Scientific Notation but how to enter a number given to you in scientific notation. Once the number is entered you do not have to do anything special. If you have to multiply it use the (x) button. to add it use the + button, etc.

How to enter a number in scientific notation.

Type in the mantissa (example 6.022)

Press the [X10^x] at the bottom of keypad.

Enter the exponent (example 23)

with this example you will have entered Avogadro's number 6.022x10^23

Other example

1.6 [X10^x] (-) 19 enters the electron charge in Coulombs. The exponent is negative that is why you press the change sign key (-).

Use the EE key (just above the 7 key) to enter an exponent. For a negative exponent, use the +- key (just to the right of the decimal point key) to enter the negative sign.

For example, to enter 1.2 x 10^-21, press 1 . 2 EE +- 2 1

To switch the display mode to scientific notation, press 2nd [SCI] (the 5 key).
