Which TI-30 Calculator Do You Have?
“TI-30” is a family name, not one model. If your teacher just says “TI 30 calculator”, check the name printed above the screen of your TI 30X scientific calculator.
| Model | Screen | Best for |
|---|---|---|
| TI-30XA | 1 line | Basic math in middle school, the cheapest TI-30 |
| TI-30X IIS | 2 lines | Shows the problem and the answer at the same time |
| TI-30XS MultiView | 4 lines, textbook style | Fractions, stats and tables. This page. |
| TI-30X Pro MultiView | 4 lines, textbook style | Adds equation solving and matrices |
Most worksheets that say TI 30X calculator mean the TI-30XS MultiView calculator, because it is the model schools buy most.
TI-30XS Key Guide
Think of this as a quick TI-30XS calculator reference sheet. These are the TI-30XS calculator keys that confuse new users most.
2nd
Uses the blue label above a key. For example, 2nd then x² gives √.
blue labels
n/d
Starts a stacked fraction. Type the top number, press the down arrow, then type the bottom number.
2nd n/d → mixed number
◄►
Switches the last answer between a fraction and a decimal, for example 3/4 and 0.75.
2nd ◄► → f◄►d
(−) and −
(−) makes a number negative. The − key is only for subtraction. Mixing them up causes a syntax error.
(−) for negatives
x yzt abc and sto→
Store a number with sto→, then press the variable key until the letter you want appears.
8 sto→ x
data and table
data opens lists for statistics. table makes a table of x and f(x) values.
2nd data → stat
delete and clear
delete removes one character. clear wipes the line, and pressing it again clears the screen.
2nd clear → clear var
How to Use Fractions on the TI-30XS
Fractions are the main reason teachers pick this calculator. Here is how to add 1/3 + 1/4 and 2½ + 1¾.
Type a fraction
Press n/d, type 1, press the down arrow and type 3. You can also type 1 first and then press n/d.
Leave the fraction
Press the right arrow to move out of the fraction, then press + and enter 1/4 the same way.
Get the answer
Press enter. The answer shows as the fraction 7/12.
Mixed numbers
Press 2nd n/d for a mixed number box. Type 2, press the right arrow, type 1, press the down arrow and type 2. Add 1¾ the same way. The answer is 4¼.
Switch the form
Press ◄► to see 4.25. Press 2nd ×10ⁿ (n/d◄►Un/d) to switch between 17/4 and 4¼.
How to Do Statistics on the TI-30XS
The TI-30XS finds the mean, standard deviation and five-number summary of a data set. Example test scores: 72, 85, 90, 64, 88, 95.
Open the lists
Press data. To empty old data, press data again and choose Clear ALL.
Type the numbers
In L1, type each score and press enter after it.
Run 1-Var Stats
Press 2nd data (stat), choose 1-Var Stats, keep DATA: L1 and FRQ: ONE, then select CALC and press enter.
Read the results
Scroll down for each value: n = 6, x̄ ≈ 82.33, Sx ≈ 11.84, σx ≈ 10.81, Med = 86.5.
Two lists? Put x values in L1 and y values in L2, then choose 2-Var Stats. You get the means of both lists plus a line of best fit, y = ax + b, and r.
How to Make a Table of Values on the TI-30XS
The table key is handy for graphing by hand. Example: f(x) = x² − 4 for x from −2 to 2.
Enter the function
Press table. After f(x)=, type x² − 4 using the x yzt abc key for x. Press enter.
Set it up
Type −2 for Start and press enter, type 1 for Step and press enter, then select OK.
Read the table
The y values are 0, −3, −4, −3 and 0. Use the up and down arrows to see more rows.
