Calculate the Permitted Calculator for the ACT

Permitted Calculators for the ACT

For the ACT, students may use any 4-function, scientific, or graphing calculator that is not on the prohibited list. Recommended models include any TI calculators between TI-30 and TI-40, TI-83 Plus, TI-84 Plus, TI-84 Plus CE, TI-84 Plus CE Python, TI-Nspire CX, and TI-Nspire CX II, as well as Casio fx-CP400 and Algebra fx 2.0 CFX-9970G.

General Guidelines

Calculators may only be used on the mathematics test and must not feature any capabilities to store text or documents, except for necessary modifications approved by ACT.

Specific Requirements

Ensure calculators needing enhancements comply by removing any paper tape, turning off sound, and covering infrared data ports with opaque material. If equipped, detach power cords during the test.

Recommendations

The TI-30 is specifically endorsed for use during the ACT. This range of calculators strikes a balance between functionality and compliance with ACT calculator policy.

Accessibility Options

Accessible calculators such as audio or Braille devices are allowed if authorized in advance, accommodating all test-takers.

Permitted Calculators for the ACT

Overview of Allowed Calculator Types

The ACT allows the use of 4-function, scientific, or graphing calculators, ensuring students have the necessary tools to tackle the mathematics test. Importantly, devices must not be on the prohibited list to be eligible for use during the exam.

Recommended Models

Models within the TI-30 to TI-40 range, such as the highly recommended TI-30, are suggested for their reliability and ease of use. The TI-84 Plus CE stands out as the top recommendation for ACT participants seeking sophisticated computational capabilities. The TI-Nspire CX also comes highly recommended, just slightly behind the TI-84 Plus CE in preference.

Specific Permitted Models

Certain specific models like the Casio fx-CP400 and the Algebra fx 2.0 CFX-9970G are directly cited as permitted for use on the ACT. These models ensure compliance with ACT's calculator policy and security requirements.

Compliance and Security Adjustments

Calculators with features that might compromise test integrity, such as infrared data ports or sound capabilities, must be appropriately modified. For instance, calculators with data ports must have these covered with opaque material, and those that make noise must have their sound turned off.

Examples of Permitted Calculators for the ACT

1. Texas Instruments TI-84 Plus

The Texas Instruments TI-84 Plus is widely accepted for ACT exams. It is capable of performing a variety of functions necessary for the math section such as solving equations and graphing. For instance, to solve 3x + 4 = 16, set the equation in the 'Y=' menu and use the graph or table view to find when Y=0.

2. Casio FX-9750GII

The Casio FX-9750GII is another excellent choice, approved for use on the ACT. It offers a high-speed processing ability to handle complex calculations efficiently. Example calculation: To compute the integral of x^2 from 0 to 5, use the 'Integral' function in the 'Math' menu.

3. HP Prime

The HP Prime is known for its advanced graphical capabilities and touch-screen interface, suitable for the ACT’s permitted calculator policy. It simplifies complex algebraic calculations, like factorizing x^2 - 5x + 6 into (x - 2)(x - 3) through its advanced CAS (Computer Algebra System).

4. Texas Instruments TI-Nspire CX

Although advanced, the Texas Instruments TI-Nspire CX meets ACT guidelines. It can solve simultaneous equations such as x + y = 10 and 2x + 4y = 20, using its algebraic capabilities to directly output x=0, y=10.

5. Casio FX-9860GII

The Casio FX-9860GII, permitted for use, enables students to calculate statistical functions, essential for the ACT math problems. For example, when analyzing data sets for mean and standard deviation, use its ‘STAT’ mode to enter data and compute these statistics efficiently.
