TI-84 + Silver Edition stuck on scientific notation

I have tried changing the mode to normal, but found out it was already on normal. Everything is showing up in scientific notation, and I need it in standard notation for Algebra.

SOURCE: ti 84 plus silver edition language change

The easiest way to fix this is through the Apps menu. Hit the apps key, then scroll down until you see any language(espanol, Deutsch, etc.). It should give you the option of switching to either that language or restoring to English. I just tried this on a calculator that was set to German. I hit Apps and scrolled down until I recognized the option for Spanish, and it still worked. It let me switch back to English.
Hope this works for you.

SOURCE: Find the antilog on the TI-84 Plus for finding pH in chemistry problems

I'm not specifically familiar with the TI83 or TI84 but I've used a lot of TI calculators in my time, so I'll give it a try. If your trying to find the antilog of a number in base 10 enter the number and hit the (10 to the X) button. If you're trying to find the antilog of a number in in base e (natural log), enter the number and hit the (e to the X) button.

SOURCE: Inputing scientific notation into my calculator


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

SOURCE: how to simplify the equations in ti 84 ??

You cannot do it with this calculator. It does not have a Computer Algebra System (CAS). Try a TI89 Titanium, a TI 92PLUS, a TI 200PLT or a TI-Nspire CAS.
However, they may exist other programs on or Search these sites and you may be lucky.

How do i divide scientific notations?

Exactly as you would any two numbers. If you are not comfortable with the notation enclose each number in scientific notation between parentheses. This way you can be sure that the priority of operations is respected.

My TI-84 Plus Silver Edition is giving regular math problems (.064/160000) an answer involving an E (4E-7) and I'm not sure how to change it.

The E is an engineering notation for 'x10^' so the answer there 4E-7 = 4 x 10^ -7 (I'm using the x as multiplication). I'm afraid there isn't a way of changing it (that I know of) but it is not difficult to learn, it's just a simple way of writing scientific notation!

When I introduce a 10^-4 I get 1E-4, how do I change it to decimals, no "E". -thanks

You can't. If the magnitude of the number is less than .001, the calculator automatically switches to scientific notation. That's just the way the calculator works.

How do you clean the e0 off the calculators?

You're seeing an exponent because you're in scientific or engineering mode. To change, press MODE and select NORMAL on the first line and either FLOAT or a number for the number of digits to the right of the decimal point.

TI-84 Plus Silver Edition. When dividing negative powers of ten by other negative powers of 10 the calculator it just adds the the negative powers together. How do i fix this? An example: 5*10^-10 /...

To enter an exponent, positive or negative, use the EE (Enter Exponent) key (the shifted function of the , key just above the 7 key). Do 5 2ND [EE] (-) 1 0 / 5 2ND [EE] (-) 1 0 ENTER and you'll see 1.

What I think you're doing (I can't be sure without seeing your keystrokes) is calculating
5*10^-10/5*10^-10 which is interpreted as (5*10^-10/5)*10^-10, which indeed is 10^-20.

No matter what problem i type in.. I get an E after the answer and sometimes the answer is not even right.. It does not matter what i type into my calculator.. i get the answer if it is a very simple...

You're in engineering notation. This is similar to scientific notation, except that exponents will always be a multiple of 3. For 8+9, you're getting 17x10^0 = 17, which of course is the correct answer.

Press MODE to enter the Mode editor. On the top line highlight NORMAL and press ENTER. On the second line highlight FLOAT and press ENTER. Press 2ND [QUIT] to exit the Mode editor.

I cannot put anything to a power over 100

Your calculator has memory limitations. The maximum exponent that you can have is 99. The largest factorial you can calculate with this calculator is 69! It value in scientific notation is 1.711224524 *10 ^98.
1E100 is considered INFINITY.
I hope you won't hold me responsible for your calculator's shortcomings.
