[BlindMath] ideas for replacement calculator

[Lorne Webber]

Greetings,

I'm asking on behalf of a colleague from another institution. A
student is in a high school pre-calculus course at a community
college, they ordered the Orion TI-30 XS but it is on back order,
would the TI-84 work as a replacement? any other models that might
work? any software calculators that might work instead?



Thanks for your assistance.

Regards,
Lorne
