Hi I need to be able to calculate 1.0 x10exp -14 divided by 5.0 x 10 exp -12. the answer should be 2.0 x 10exp -3
SOURCE: The calculator won't convert fractions into decimals
Are you using a ti-89? If so, check your mode settings and change Exact to Approximate.
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.

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

Hello,
Increase the number of decimal digits. Here is a clipping of the guide to help you configure calculator. I hope it helps.

Hello,
Your notation expression contains an extra symbol ( either the - or the second x).
If I enter
(1.9x10^10)x453.6/163871 I get 5.262148845 x 10^7 about 5.3 x10^7
If I enter
(1.9x10^10 - 453.6)/163871 I get 1.159 x 10^5.
Your result is off by a factor of 100 to 10000.
As to the scientific display mode, you set it by pressing [MODE][->][SCI][ENTER] [2nd][QUIT]. You can leave the Float option to 9 digits if you want.
Hope it helps.
