Question about Texas Instruments TI-83 Plus Calculator

Scientific notation I used scientific notation once to enter a number. Now all the answers I receive from the calculator are in scientific notation, even small numbers. How do I make it so that the answers will return to normal form?

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

My casio FX 991ES is giving formula answers, to a calculation using a large exponent number in a formula answer, I need it to tell me a long number instead. Sum is 6.7 x 1018. The answer I get is 6.7x1018,...


Your answer is 6.7*10^18. That requires 19 places on the display: There are not enough places to write that. Besides, calculators are deigned to use Scientific Notation whenever the result to be displayed is too large or too small.
If you enjoy writing zeros, convert by hand the scientific notation into what you call long number.

Casio fx-115ms OR ANY scientific calculator


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.

How are numbers in scientific notation entered in Aurora SC150X calculator


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.

How do i convert a number in scientific notation using the calculator?


You can always enter a number in scientific notation. Use the EE or the [x10^X] key to enter the exponent of 10. Whether it will remain in that form depends on the display mode you set the calculator into:SCI, ENG, NORM1, NORM2, FIX.
However if a result is too big or too small, it will always be represented in SCIentific format.

I need to know how to divide, mutiply, add, and substract in scienctific notation on my Casio fx-300ES


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 (-).

Hoe do you use logarithm on TI-36X SOLAR?


Basically you first have to put your answer into scientific notation by pressing the 3rd key then the 6 key. The screen display should change to one big zero and two small zeros.

I was workinggon the same problem with a -log of a chemistry problem to get pH and I knew the answer because I calculated it on it TI-85, but we are not allowed to use graphing calulators on the exam (:-((() so I had to figure out how to do it on this one!

For example, I had pH =-log(2.828947x10^4)

On the TI-36X you change to scientific notation using the instructions above. Once the three zeros enter on the screen:
[4]
[-]
[2nd]
[10^x]

1^-04 should appear on screen, then you multiply by 2.828947

[x]
[2][.][828947]
then your screen will show the answer in scientific notation.

2.828947 in big numbers and in small numbers -04
From there you simply press:
[log]
and your answer will show up as a negative number. Just take the absolute value of that and you have your answer. Took me like 30 minutes the night before a huge chemistry exam to figure that out! Hope it helps someone!

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
