There is something wrong with the scientific notation on my calaculator. I put in 0.030377/6.022x10^23 ang get 5.044337429x10^20 then i divide that by 1000 and get 5.044337429x10^17 when the answer should be 5.044x10^-29. How do I fix it??

Sorry, but there is nothing wrong with the exponential notation on your calculator. There is however a misunderstanding from your part on the priority rule of operations.

The sequence 0.030377/6.022x10^23 is interpreted as (0.030377/6.022)x10^23 while you wanted 0.030377/(6.022x10^23), dividing by Avogadro's Number.

How to fix it. Enter the power of 10 exponent (10^23) using the EE key. In other words Avogadro's Number should be typed in as 6.022 [EE]23. If you do not have the EE key you must use parentheses to enclose the whole number (6.022x10^23) or use the division key twice /6.022/10^23

On a calculator a sequence a/bxc where both operations have the same level of priority is executed from left to right.

SOURCE: scientific notation

you want to hit mode not menu and then make sure that normal is flashing instead of SCI and hit enter. so just hit mode then enter and it should be normal

Posted on Jan 14, 2008

SOURCE: how to convert a normal ANSWER to scientific

It's been a while since my TI calculator died, but I think you can just hit EE (may be "exp" on your model) followed by =.

SOURCE: I have a TI-30XS Calculator

One solution that you might try is to put the scientific numbers in parentheses. For instance open parenthesis, type in the first scientific notation then close parenthesis, next hit the divide key and then open parenthesis and type in the 2nd number in scientific that you are dividing by and then close parenthesis. Hit enter or =. I'm not sure if this will fix your problem, but it is worth a try.

SOURCE: Inputing scientific notation into my calculator

Hello,

1. To convert a number to scientific equation, use [2nd][Sci]

Exemples 12345 [=] screen shows 12345 Then [2nd][Sci] coverts it to 1.2345 ^04 to the power 4.

2. To enter directly a number in scientific notation (e.g. -1.2345 X10^(-65) a very small number) you use the [EE] key 1.2345[+ /-][EE][+/-]65 shows as -1.2345 -65

1.6X10^(-19) 1.6[EE][+/-]19 shows as 1.6 -19

Hope it helps

I get the same answer. Is b wrong? When I do it in Excel I get b= -2E+06, which is -1 797 322.99 rounded to the millions, in scientific notation.

Let me know if you have any questions.

Good luck,

Paul

I am not sure what you mean. Even politicians use the term exponential so it has become blurry.

16=2^4 The power function is related to the exponential.

16=1.6*10^1 Scientific notation. Scientific notation is an exponential display format.

Take your pick.

In main screen press 4:Settings then 2: Document Settings. On the third line Exponential Format, set Scientific. Validate by pressing OK..

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.

If the absolute value is less than 0.001 then the TI-84 automatically switches to scientific notation. This is just the way the calculator works.

Sorry if that wasn't the answer you wanted to see, but there it is.

Hello,

Frankly, I do not understand what you want.

I will try to guess.

Calculate the exponential of 135

Use the [2ndF][LN] key to access the exponential e^x

[2ndF][e^x] 135 [=] result is 4.263389948 x 10^(58)

or 4.263389948E 58

Represent 135 in scientific notation

135 =1.35 x10^2 or 1.35 E2

Represent 135 in Engineering Notation

135=135E0

If none of the above answers your question, maybe you should state clearly what you want, I am no seer.

Hope it helps.

Hello,

I am only looking for a plausible cause of the error, because I do not believe your calculator can make such a mistake. I think you**accidentally activated the Exponential display format** and did not pay attention to the small, raised -03 that came at the end of the number displayed. It is a common mistake for those not very familiar with Scientific or exponential notation.

Let us try to reset your calculator to the normal (floating point) format.

Press the [MODE] key a number of times until you reach a screen that has FIX, SCI, NORM and under each one a number (FIX 1, SCI 2), Norm 3). To have the number of decimal place you gave in your result (4 decimal digits), you press 1 to select Fix then 4.

Be aware that scientific calculators usually stop displaying results in floating point format ( 0.0000045 ) if the number is smaller then 0.001. So basically, 0.00099 will be displayed as 9.90-04, -04 being raised above the level, and in smaller size.

Hope it helps.
