Or maybe you’ve decided it’s time to ditch that old TI-83 in favor of a new color TI-Nspire CX. Or possibly you’re a parent who’s last child has finished their last math class and you’d like to recoup some of the money you invested in a graphing calculator for your kids.
Just received an email from marketing at Texas Instruments alerting me that they released a new operating system for the TI-84 plus a couple of days ago. The newest release for the TI-84 is 2.55MP.
