What Are Funny Things To Do On A Calculator?
“Funny things to do on a calculator” often refers to the classic pastime of calculator spelling, a clever trick that turns numbers into words. This unintended feature of seven-segment displays on calculators allows certain digits, when viewed upside-down, to resemble letters of the Latin alphabet. By typing a specific sequence of numbers and then flipping the calculator, a hidden word or phrase is revealed. This form of amusement, sometimes known as ‘beghilos’ after the letters that can be formed (B, E, G, H, I, L, O, S), became incredibly popular in schools during the 1970s and 80s, offering a delightful distraction from math class. Anyone with a basic calculator can try this, making it one of the most accessible and funny things to do on a calculator. A common misconception is that any word can be spelled, but the practice is limited to the specific letters that the digits can represent.
The “Formula” and Mathematical Explanation for Calculator Spelling
The process behind these funny things to do on a calculator isn’t a mathematical formula but a simple two-step algorithm: reversal and substitution. First, to spell a word, you must type the corresponding numbers in reverse order. For example, to spell “HELLO,” you would enter the numbers for O, L, L, E, H in sequence (0.7734). Second, after flipping the calculator, your brain performs a character substitution based on the shapes of the upside-down digits. This is the core of all funny things to do on a calculator involving words.
The step-by-step derivation is as follows:
- Choose a target word (e.g., “SHELL”).
- Map each letter to its corresponding number: S=5, H=4, E=3, L=7.
- Reverse the order of the letters: L-L-E-H-S.
- Type the corresponding numbers into the calculator: 77345.
- Flip the calculator 180 degrees to read the word “SHELL”.
| Variable (Number) | Meaning (Letter) | Unit | Typical Range |
|---|---|---|---|
| 0 | O | Alphanumeric | 0-9 |
| 1 | I | Alphanumeric | 0-9 |
| 2 | Z | Alphanumeric | 0-9 |
| 3 | E | Alphanumeric | 0-9 |
| 4 | h | Alphanumeric | 0-9 |
| 5 | S | Alphanumeric | 0-9 |
| 6 | g | Alphanumeric | 0-9 |
| 7 | L | Alphanumeric | 0-9 |
| 8 | B | Alphanumeric | 0-9 |
| 9 | G | Alphanumeric | 0-9 |
Practical Examples of Funny Things To Do On A Calculator
Let’s explore some real-world examples that demonstrate the core of these funny things to do on a calculator. These examples show how to combine numbers to create classic words.
Example 1: Spelling “BOOBIES”
This is arguably the most famous example of calculator spelling, dating back to the 1970s.
- Inputs: The number typed is
5318008. - Process: The calculator display shows 5318008. When flipped upside down, the 8 becomes B, the 0 becomes O, the 1 becomes I, and the 5 becomes S. However, the classic spelling reverses the S to a second B, using the number 8 at both ends. The correct number is 5318008. When flipped, it reads BOOBIES.
- Outputs: The main result is the word “BOOBIES”. This cheeky word became a staple of schoolyard humor and a perfect example of funny things to do on a calculator.
Example 2: Spelling “SHELL OIL”
A more complex and commercial example shows how phrases can be created.
- Inputs: The number typed is
71077345. - Process: The number is entered directly. When the calculator is turned upside down, the sequence of numbers translates as follows: 5 -> S, 4 -> H, 3 -> E, 7 -> L, 7 -> L, 0 -> O, 1 -> I, 7 -> L. But to spell SHELL OIL correctly, you need to type 71077345. Flipped, it reads “SHELLOIL”.
- Outputs: The result is the phrase “SHELL OIL,” demonstrating how this fun trick can even spell out brand names, making it one of the more creative and funny things to do on a calculator.

Key Factors That Affect Calculator Spelling Results
While it seems simple, several factors can influence the outcome and variety of these funny things to do on a calculator.
- Calculator Display Type: The classic seven-segment display is essential. Modern calculators with dot-matrix screens show numbers too clearly, ruining the illusion.
- Available Digits: You are limited to the letters formed by the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. This limited alphabet is why it’s a creative challenge.
- User Creativity: The core of finding funny things to do on a calculator is your own imagination. Thinking of words that fit the limited alphabet is the main part of the fun.
- Word Length: Longer words are harder to create. Words like “gLOSSOLOgIES” and “hILLBILLIES” are considered major achievements in the calculator spelling community.
- Inclusion of the Decimal Point: The decimal point doesn’t map to a letter and is often ignored, but its placement is crucial for creating certain number sequences, like in 0.7734 for “HELLO”.
- Cultural Language: While most words are in English, some number sequences can spell words in other languages, adding another layer to the fun. Exploring these is one of the more advanced funny things to do on a calculator. For more on word games, see our {related_keywords} page.
