About TI-34 Calculator Online
The TI-34 MultiView is the calculator many upper elementary and middle school classrooms use to learn fractions, percents and pre-algebra. This TI-34 calculator online gives you the same four-line screen and the same special keys, free in your browser.
The TI-34 is built for learning, not just for answers. It can simplify a fraction one step at a time, show the remainder of a division and repeat an operation so students can see a pattern. Those tools make it different from other scientific calculators.

TI-34 Special Keys Explained
These keys are what make the TI-34 MultiView calculator different. Here is what each one does.
simp
Simplifies the last fraction by its smallest common factor, or by a factor you type. Press it again to keep going.
simp, then enter
Int÷
Divides two whole numbers and shows the quotient and remainder, for example 5 r 2.
2nd ÷
op1 and op2
Store an operation such as +4 or ×2, then press op1 to apply it again and again.
2nd op1 to set
%
Turns a number into a percent in a calculation. 2nd % (▸%) changes an answer into a percent.
% key
n/d and U n/d
Enter a fraction or a mixed number. 2nd U n/d switches an answer between mixed and improper form.
fractions
◂▸
Switches the last answer between a fraction and a decimal.
2nd ◂▸ → f◂▸d
trig, log and math
sin, cos, tan and log are in menus: 2nd π opens trig and 2nd √ opens log. The math key holds lcm, gcd, abs and round.

How to Simplify Fractions on the TI-34
With SIMP set to MAN in the mode screen, the TI-34 does not reduce fractions for you. You simplify step by step and see the factor each time. Example: 24/36.
Set manual simplifying
Press mode, move down to SIMP, choose MAN and press enter, then clear.
Enter the fraction
Type 24, press n/d, type 36 and press enter. The answer stays 24/36.
Simplify
Press simp enter. The screen shows Fac=2 and 12/18.
Keep going
Press simp enter twice more: Fac=2 gives 6/9, then Fac=3 gives 2/3.
Use your own factor
To divide by 12 in one step, press simp, type 12 and press enter.
How to Divide with Remainders on the TI-34
Long division homework often wants the answer as a quotient and a remainder. The Int÷ key does this in one step.
Type the first number
Type 17.
Use Int÷
Press 2nd ÷, then type 3.
Read the answer
Press enter. The screen shows 5 r 2, which means 17 ÷ 3 is 5 with a remainder of 2.
How to Use op1 and op2 on the TI-34
op1 and op2 save an operation so you can repeat it. They are great for skip counting, patterns and sequences. Example: start at 3 and keep adding 4.
Store the operation
Press 2nd op1, then type +4 and press enter.
Start the pattern
Type 3 and press op1. The answer is 7.
Repeat
Press op1 again for 11, and again for 15. Each press adds 4 to the last answer.
Two patterns at once: store ×2 in op2 to compare doubling with adding 4. This is a common way to explain linear and exponential growth.
How to Do Percent Problems on the TI-34
The TI-34 has its own % key, so percent problems are quick.
| Problem | Press | Answer |
|---|---|---|
| 25% of 80 | 25 % × 80 enter | 20 |
| 3/8 as a percent | 3 n/d 8 → 2nd % enter | 37.5 |
| Price after 20% off $45 | 45 − 20 % × 45 enter | 36 |

Quick answers about the TI-34
What grade is the TI-34 MultiView for?
Mostly grades 5 to 8. It covers fractions, percents, pre-algebra and basic statistics, and many students keep using it in high school.
Is the TI-34 allowed on the SAT and ACT?
Yes. It is a scientific calculator, which both tests allow. Online calculators cannot be used in the test room.
Is the TI-34 a graphing calculator?
No. It is a scientific calculator. For graphs, use our TI-84 calculator online.
How do you simplify fractions on a TI-34 calculator?
Use the simp key. Enter the fraction, press simp and enter. Repeat until the screen shows the same fraction.
What is the difference between the TI-34 and TI-30XS?
Learning tools. The TI-34 adds simp, Int÷ and op1/op2. The TI-30XS adds a table and quicker trig and log keys.
Is this TI-34 calculator online free?
Yes. It is a free TI-34 calculator online with no download or sign-up.
