Can You Use a Calculator on the Whole ACT Math Section?

A detailed guide and interactive checker for the official 2026 ACT calculator policy.

What Does “Can You Use a Calculator on the Whole Math ACT Section?” Mean?

This is a very common and important question for students preparing for the ACT. The simple answer is **yes, you are permitted to use a calculator on the entire 60-minute, 60-question ACT Math Test**. Unlike other standardized tests, the ACT does not have a “no-calculator” section within the math test. However, this permission comes with a strict set of rules about what kind of calculator you can use. The phrase “can you use a calculator on the whole math act section” is less about which parts of the test allow it, and more about whether your specific calculator model is approved for use at all.

The ACT’s policy is designed to ensure fairness and prevent any student from having an unfair advantage through technology. All questions on the ACT Math Test can be solved without a calculator, but using an approved one effectively can significantly help with speed and accuracy on more complex problems.

The “Formula” for an ACT-Approved Calculator

There isn’t a mathematical formula, but there is a logical one to determine if your calculator is allowed. Think of it like this:

Permitted = (Is a 4-Function, Scientific, or Graphing Calculator) AND (Is NOT on Prohibited List) AND (Has NO Prohibited Features)

A calculator is generally prohibited if it has features that go beyond numerical calculations, such as solving algebraic equations for you or accessing the internet. Let’s break down the variables.

Variables in the ACT Calculator Policy

Key factors determining calculator eligibility.

Variable / Factor	Meaning	Unit/Type	Typical Status
Calculator Type	The basic category of the calculator.	Categorical	4-function, scientific, and graphing are usually permitted.
Computer Algebra System (CAS)	A feature that can solve symbolic algebra, find derivatives, etc.	Boolean (Has/Doesn’t Have)	Strictly Prohibited.
QWERTY Keyboard	A keyboard laid out like a computer/typewriter.	Boolean (Has/Doesn’t Have)	Strictly Prohibited.
Wireless Communication	Any feature like Wi-Fi, Bluetooth, or Infrared (IR).	Boolean (Has/Doesn’t Have)	Prohibited. IR ports must be covered.
External Power	The need for a power cord to operate.	Boolean (Needs/Doesn’t Need)	Prohibited; must be battery-operated for the test.

Practical Examples of Calculator Eligibility

Example 1: A Permitted Calculator

• Inputs: Calculator Model: “TI-84 Plus CE”. Features: No CAS, no QWERTY keyboard.
• Analysis: The TI-84 Plus series is one of the most common and widely accepted graphing calculators for the ACT. It performs graphing and complex numerical calculations but does not have a prohibited Computer Algebra System.
• Result: **Permitted**. This calculator is perfectly acceptable for the whole math ACT section.

Example 2: A Prohibited Calculator

• Inputs: Calculator Model: “TI-89 Titanium”. Features: Has a Computer Algebra System (CAS).
• Analysis: The ACT explicitly prohibits all calculators with CAS functionality. The TI-89 is a powerful tool, but its ability to perform symbolic algebra gives users an unfair advantage according to the rules.
• Result: **Prohibited**. This calculator cannot be used on the ACT Math Test.

How to Use This ACT Calculator Policy Checker

1. Enter Your Calculator Model: Type the model of your calculator into the first input field. This helps check against specific models that are banned by name (e.g., TI-89, HP 50G).
2. Select Prohibited Features: Carefully review the checklist. If your calculator has any of those features (like a QWERTY keyboard or CAS), check the corresponding box.
3. Check Eligibility: Click the “Check Eligibility” button to see the result.
4. Interpret the Results: The tool will give you a clear “Permitted” or “Prohibited” status and explain the reason. The compliance bar provides a quick visual confirmation.

Key Factors That Affect if You Can Use Your Calculator on the Whole Math ACT Section

Understanding these factors is crucial for test day. A wrong choice can lead to being dismissed from the test.

1. Computer Algebra System (CAS): This is the most common reason for a graphing calculator to be banned. Models like the TI-Nspire CAS, TI-89, and HP Prime are prohibited for this reason.
2. QWERTY Keyboards: Any device with a typewriter-style keyboard is not allowed. This prevents the use of devices that are essentially pocket computers.
3. Communication Capabilities: Calculators with Wi-Fi, Bluetooth, or even infrared ports are banned. If your calculator has an IR port (like some older HP models), you must cover it completely with opaque tape.
4. External Power Source: Your calculator must be battery-powered. You cannot have it plugged into an outlet during the test.
5. Noise and Printing: If your calculator makes noise, it must be muted. If it uses paper tape, the tape must be removed before the test.
6. Device Type: You cannot use the calculator function on a phone, tablet, smartwatch, or laptop. The device must be a dedicated calculator.

Frequently Asked Questions (FAQ)

Is the ACT Math test split into calculator and no-calculator sections?

No, unlike the SAT, the entire ACT Math test allows the use of an approved calculator. You have access to it for all 60 questions.

What happens if I bring a prohibited calculator?

The testing staff will inspect calculators. If you are found with a prohibited device, you may be dismissed from the test, and your score will be voided.

Is a TI-Nspire allowed?

It depends on the model. The TI-Nspire CX (non-CAS) and TI-Nspire CX II (non-CAS) are PERMITTED. However, the TI-Nspire CX CAS and CX II CAS are PROHIBITED. Check the top of your calculator screen for the “CAS” designation.

Do I need a graphing calculator?

No, all questions can be solved without a calculator. However, a graphing calculator can be a very helpful tool for solving problems related to functions, coordinate geometry, and trigonometry. A familiar scientific calculator is better than an unfamiliar graphing calculator.

Are there any programs I need to remove from my calculator?

Yes. The ACT states that calculators may not have any programs that include CAS functionality. While proctors rarely check program memory, it is against the rules to have games or formula programs stored on your device. It is safest to clear the memory before the test.

What about the online ACT? Is there a built-in calculator?

Yes, for students taking the computer-based ACT, there is an on-screen calculator available. It is similar to the Desmos graphing calculator. You are typically still allowed to bring your own approved handheld calculator as well.

Can I share my calculator with someone else?

No, sharing calculators during the test is strictly forbidden.

What’s the best advice for choosing a calculator?

Use a calculator you are already familiar and comfortable with. Don’t buy a new, complicated calculator right before the test. Ensure it’s on the approved list and has fresh batteries. Bringing a backup is also a great idea. If you’re looking for more tips, consider researching {related_keywords}.
