TI calculators have an OS (operating system) that can be upgraded. To see what OS your calculator has do the following:
|
|
- Select 2nd and then mem (mem is above the + key)
|

|
- Select 1: About
- This TI-84 Plus has OS 2.55MP
|

|
- This TI-84 Plus CE has OS 5.2.1.0042
|
 |
- Apparently, the newest OS for the TI-83 is OS 19
|
|
- If you have an older OS your calculator may not behave like calculators with the newest OS. Here’s one difference between older OS’s and the newer OS’s
|
|
- For some older OS’s when you enter a number and then press ^ you can only enter one digit. So, for example if you want, to take 5 to the 31 power it’s difficult because after you enter the 3, the cursor drops down to normal mode. You’ll need to bracket the power with parentheses.
|

|
- For newer OS’s, the cursor stays in the exponent place until you press enter or the ► key.
|

|
- To upgrade the OS on your calculator you’ll need to download two files from TI. The first file is the new OS. The second file is a program that writes the new OS to your calculator. You’ll also need a cable to connect your calculator to your PC.
