It’s powered by a lithium battery, ensuring consistent performance, but it does not include advanced features like graphing or programmability.
Pros:
- Two-line display showing input and results
- Supports scientific and statistical functions
- Multiple angle modes for varied calculations
Cons:
- Limited to basic scientific functions, no graphing
- Small display size may be challenging for some users
- Less durable plastic enclosure
Best for: Budget-conscious students who need a reliable scientific calculator for everyday use
Not ideal for: Those requiring graphing capabilities or advanced programming features
Bottom line: A solid, budget-friendly choice that covers the essential scientific functions for high school students without extra bells and whistles.

Texas Instruments TI-30XS MultiView Scientific Calculator
The TI-30XS MultiView introduces a multi-entry display that allows students to enter and compare multiple calculations side-by-side—ideal for exploring patterns and checking work. Its support for scientific, statistical, and table functions makes it versatile for various math and science topics. Unlike the other two models, it displays math notation such as fractions, exponents, and square roots directly, aiding comprehension. However, it lacks a backlit display, which limits usability in low-light environments, and it doesn’t support graphing or programming. This makes it best suited for classroom settings where multiple calculations need to be compared or for students who prefer a more visual approach to math.
Pros:
- Multiple calculations visible simultaneously
- Supports math notation including fractions and exponents
- Includes table of values for functions
Cons:
- No backlit display for low-light conditions
- Limited to scientific and basic math functions
- No graphing capabilities
Best for: Students who need to compare calculations or explore functions visually
Not ideal for: Users needing graphing, high-level programming, or working in poorly lit areas
Bottom line: The MultiView model is perfect for students who want to compare multiple calculations and visualize functions without the complexity of graphing features.

Before You Start
Check that your calculator is functioning properly. Clear previous calculations if necessary to avoid confusion. Review the calculator’s manual for specific functions if available.
Step-by-Step Instructions
Step 1: Power on the calculator
Press the ‘ON’ button to turn on the calculator. Wait for the display to light up and show the default screen or previous calculations cleared.
Tip: If the calculator does not turn on, check the batteries or power source.
Check: The calculator displays a blank or default screen, ready for input.
Step 2: Set the calculator mode
Press the ‘MODE’ button, then select the appropriate mode for your calculations, such as ‘Degree’ or ‘Radian’ for angles, or scientific notation if needed. Confirm your choice.
Tip: Use the arrow keys if available to navigate options. Correct mode ensures accurate trigonometric or exponential calculations.
Check: The mode displayed matches your calculation needs, such as ‘Deg’ or ‘Rad’.
Step 3: Perform basic calculations
Input simple calculations like addition (e.g., 25 + 17), subtraction, multiplication, or division. Use the number keys and operation keys, then press ‘=’ to see the result.
Tip: Double-check operators before pressing ‘=’ to avoid mistakes. Use parentheses for complex expressions.
Check: The display shows the correct result, e.g., 25 + 17 = 42.
Step 4: Use advanced functions
Learn to access functions like powers, roots, logarithms, and trigonometry. Use the dedicated keys (e.g., ‘^’ for powers, ‘√’ for square roots, ‘log’ for logarithms, ‘sin’, ‘cos’, ‘tan’ for trigonometry).
Tip: Consult the manual for functions not immediately apparent. Practice with sample inputs to confirm understanding.
Check: Calculations involving advanced functions produce expected results, e.g., sin(30) ≈ 0.5.
Step 5: Use memory functions (if available)
Press ‘SHIFT’ or ‘ALPHA’ followed by the memory key (e.g., ‘M+’, ‘MR’, ‘MC’) to store and recall values during calculations.
Tip: Avoid overwriting stored memory unintentionally by keeping track of stored values.
Check: Values stored and recalled correctly, aiding in multi-step calculations.
Step 6: Clear previous entries and errors
Press ‘AC’ or ‘SHIFT’ + ‘CLR’ to clear the current calculation and reset the calculator for new input.
Tip: Clear before starting a new calculation to prevent residue errors.
Check: Display resets to default, ready for new input.
Common Mistakes to Avoid
- Entering calculations in the wrong mode (e.g., degrees vs. radians) — Always set the correct mode for your calculations before starting.
- Forgetting to parentheses when combining operations — Use parentheses to group operations correctly, especially in complex expressions.
- Using an incorrect function key or notation — Familiarize yourself with your calculator’s layout and function keys through the manual or practice.
- Not clearing the calculator before starting a new calculation — Press ‘AC’ or ‘CLR’ to reset before each new calculation to avoid errors.
Troubleshooting
Problem: Calculator displays an error message (e.g., ‘Math Error’)
Solution: Check your input for mistakes, such as incorrect parentheses, division by zero, or invalid functions. Correct the input and try again.
Problem: Results seem incorrect or inconsistent
Solution: Verify the calculator’s mode (degrees/radians) and function settings. Re-enter the calculation carefully.
Problem: Calculator won’t turn on
Solution: Replace or recharge the batteries. Confirm the power switch is engaged.
Problem: Function keys do not respond
Solution: Reset the calculator, or consult the manual to ensure the correct mode is active.
