can you use the ti-84 calculator on the act Formula and Mathematical Explanation
There is no complex formula, but the decision can be expressed as a logical expression:
Allowed = ModelAllowed AND BatteryOK AND AppsOK
Where:
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| ModelAllowed | True if model meets ACT criteria | Boolean | True/False |
| BatteryOK | True if using AA batteries | Boolean | True/False |
| AppsOK | True if no prohibited apps or custom programs | Boolean | True/False |
Practical Examples (Real-World Use Cases)
Example 1: Student has a TI‑84 Plus CE, uses AA batteries, no custom programs.
