The TI-84 has ruled math classes for decades. Can cheaper calculators gain ground?

The dominance of Texas Instruments' TI-84 calculator in math classes is being challenged as SAT and AP tests provide free digital graphing alternatives, yet school districts remain loyal to the established brand. The entrenched preference for TI-84s, despite the availability of cheaper options, highlights a broader issue in educational technology adoption where familiarity and brand loyalty often trump cost savings. This shift could signal a potential change in how educational tools are chosen, impacting both students and the tech industry.
