Simplified Logic:

A calculator is generally allowed if:

• It is a graphing, scientific, or basic four-function calculator.
• It does NOT have prohibited features like wireless communication, internet access, smartphone capabilities, external data storage, or advanced programming (like CAS).
• It is not a prohibited electronic device like a phone, tablet, or smartwatch.
