The TI-84 Plus CE series is a line of graphing calculators manufactured by Texas Instruments (TI). The original TI-84 Plus CE superseded the TI-84 Plus series upon its introduction in 2015; together with the TI-Nspire series, the TI-84 Plus CE is the current flagship series of Texas Instruments graphing calculators.
In 2020, TI Education announced its decision to remove support for assembly and C programming on these calculators in response to a video posted on YouTube detailing how to bypass the test mode on OS version 5.2.2. Texas Instruments' response was widely considered unnecessary and led to anger from users. The changes are reflected in OS version 5.5.1 for the European models and OS version 5.5.5 for the US models.
