ACT Math Calculator Strategy Guide

## ROLE
You are an ACT Math expert who knows exactly when and how to use a calculator effectively on the test.

## CONTEXT
Calculators are allowed on all ACT Math questions, but using them inefficiently can waste time. I need strategic calculator usage skills.

## TASK
Create a calculator strategy guide:

**CALCULATOR TYPE OPTIMIZATION**

*For TI-84 Users*
- Essential Functions: [list with button sequences]
- Time-Saving Programs: [if allowed]
- Memory Usage: [storing frequently used values]

*For TI-Nspire Users*
- Key Advantages: [CAS features if available]
- Graph Functions: [how to use effectively]

**WHEN TO USE CALCULATOR**

*Always Use For*
- [Calculation type 1]
- [Calculation type 2]
- [Calculation type 3]

*Never Use For*
- [Task better done mentally]
- [Task where calculator slows you down]

*Judgment Call*
- [Situations where it depends]

**PROBLEM TYPE STRATEGIES**

*Arithmetic*
- Calculator Role: [when to use]
- Mental Math Alternative: [when faster]

*Algebra*
- Solving Equations: [graphing vs. algebraic]
- Systems of Equations: [calculator approach]

*Geometry*
- Trig Calculations: [degree mode warning]
- Area/Volume: [formula vs. calculation]

*Statistics*
- Mean/Median: [list functions]
- Standard Deviation: [if you have time]

**CALCULATOR SHORTCUTS**
| Task | Shortcut | Time Saved |
|------|----------|------------|
| [Common task] | [button sequence] | [seconds] |
[Continue]

**PRE-TEST SETUP**
- [ ] Fresh batteries
- [ ] Degree mode (not radians)
- [ ] Memory cleared
- [ ] Brightness adjusted

**COMMON CALCULATOR ERRORS**
1. [Error type]: [how to avoid]
2. [Error type]: [how to avoid]

## INPUT
Calculator Model: {calculator}
Weakest Math Areas: {weak_areas}
