Wrong exponential/scientific notation answer

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??

    Could you post the exact sequence of keys you're pressing? Also, you posted this question under two different calculator models. Which one are you using?

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

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 =.

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.

Hello,
Use the EE key
1.234[EE] [(-)]65 [ENTER] 1.234 times 10 negative 65 =1.234E-65
The (-) is not the regular (bigger) minus sign.
Hope it helps

I cant figure out the exponential form for 16


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.

Wrong exponential value


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.

I am using my Casio fx-300MS and have somehow gotten into the display where it puts my answers in exponential form; 5+5 = 1.0 exp10 to the 1. How do I return to getting my answers in standard form?


Display Format

To change the exponential display format, press the [MODE] key 3 times.

Fixed number of decimal places:

Press 1: Scientific Notation: 0

Press 2: SCI: 0

Press 3: NORM

You will then be prompted for NORM 1 or NORM 2. CHOOSE NORM 1


To return the calculation mode and setup to the initial defaults, press [SHIFT] [CLR] [2]

[=]. This will return the calculator to the following settings:

Calculation mode COMP

Angle unit Deg

Exponential display format Norm 1

Fraction display format a b/c

Decimal point character Dot

I have a TI30XA calculator and want to know how to multiply numbers using scientific notation. I have learned how to enter a number (e.g., 1.5 x 10 -6), but when I try to multiply it by something (e.g.,...

Whats the exponential form of 135


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.

Hi, I have a Casio calculator fx-991MS giving me wrong answers!


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.
