What are Things to Write With a Calculator?

“Things to write with a calculator,” often known as calculator spelling or beghilos, is the nostalgic practice of typing a sequence of numbers into a simple calculator, then turning the device upside-down to reveal a word. The shapes of the seven-segment display digits resemble letters of the alphabet when inverted. For instance, the number ‘3’ becomes ‘E’, ‘7’ becomes ‘L’, and ‘0’ becomes ‘O’. This clever trick has been a source of amusement in classrooms for decades, allowing for secret messages and silly jokes long before smartphones existed.

This calculator is for anyone looking to relive that classroom fun, from students to adults feeling a bit nostalgic. A common misconception is that any word can be spelled, but the practice is limited to a specific set of letters (B, E, G, H, I, L, O, S, Z). Finding creative things to write with a calculator is part of the challenge and fun. The most famous example is ‘5318008’, which spells ‘BOOBIES’ upside down—a classic piece of schoolyard humor.

The “Formula” Behind Things to Write With a Calculator

There isn’t a mathematical formula in the traditional sense. The “formula” is a two-step translation process: first, the word is spelled backward, and second, each letter is substituted with its corresponding number. This is because when you flip the calculator, the order of digits is reversed.

For example, to spell “hello”:

1. Reverse the word: “olleh”
2. Substitute each letter: ‘o’ -> 0, ‘l’ -> 7, ‘l’ -> 7, ‘e’ -> 3, ‘h’ -> 4
3. The number to type is 07734. Some add a decimal (0.7734) to make it feel more like a calculation result.

This process is the core logic for all things to write with a calculator. Our tool automates this for you.

Variable (Letter)	Meaning (Number)	Upside-Down Appearance	Typical Range
O	0	O	Always used
I	1	I	Always used
Z	2	Z	Less common
E	3	E	Very common
H	4	h	Common
S	5	s	Very common
G	6	g	Infrequent
L	7	L	Very common
B	8	B	Common

This table explains the variables used in calculator spelling, a key part of finding things to write with a calculator.

Practical Examples of Things to Write With a Calculator

Example 1: “shell”

• Input Word: shell
• Process: The word reversed is “llehs”. Substituting letters gives ‘l’->7, ‘l’->7, ‘e’->3, ‘h’->4, ‘s’->5.
• Calculator Input: 77345 (or 5.4375 if you’re trying to hide it!)
• Interpretation: This is a classic, simple word that demonstrates the core convertible letters perfectly. It’s one of the most common things to write with a calculator.

Example 2: “boobless”

• Input Word: boobless
• Process: Reversed is “sselboob”. Substitution gives ‘s’->5, ‘s’->5, ‘e’->3, ‘l’->7, ‘b’->8, ‘o’->0, ‘o’->0, ‘b’->8.
• Calculator Input: 55378008
• Interpretation: This is a longer, more advanced example often told as part of a story or joke, showcasing how multiple letters can be combined for humorous effect. It’s a prime example of the funny things to write with a calculator.

Key Factors for Good Calculator Words

Not all words are created equal when it comes to calculator spelling. Here are key factors that affect the quality and readability of things to write with a calculator.

• Letter Availability: The most crucial factor. The word must be composed primarily of the letters B, E, G, H, I, L, O, S, and Z. Words with letters like M, W, V, or K are impossible to spell.
• Word Length: Longer words are often more impressive, but they are harder to find. A word like “hillbillies” (53177187714) is a rare gem. Shorter words are more common.
• Readability: Some number-letter combinations are clearer than others. ‘7’ as ‘L’ is very clear, whereas ‘6’ as ‘g’ can be a stretch on some displays. The best things to write with a calculator are those that are instantly recognizable.
• Context and Humor: The most memorable calculator words are often funny or slightly mischievous, like the infamous ‘80085’ (BOOBS). The context of a classroom or a shared joke enhances their impact. For other fun math topics, check out our article on fun math tricks.
• Calculator Display Type: The classic 7-segment LCD or VFD screens are the best for this trick. Modern high-resolution or dot-matrix displays may render the numbers too clearly, ruining the illusion.
• Memorability: Simple, catchy phrases like “hello” (07734) are easy to remember and share, making them popular choices for things to write with a calculator.

Frequently Asked Questions (FAQ)

1. What is the most famous calculator word?

By far, the most famous is ‘80085’ or ‘5318008’, which spell ‘BOOBS’ and ‘BOOBIES’ respectively. They are quintessential examples of the silly humor associated with things to write with a calculator.

2. Why do you have to reverse the word first?

When you physically flip a calculator upside down, the last digit you typed appears first. You must reverse the word’s spelling to counteract this physical inversion. Thinking about your age calculator results in reverse isn’t as fun!

3. What letters cannot be used?

A majority of the alphabet cannot be formed on a 7-segment display. Letters like A, C, D, F, J, K, M, N, P, Q, R, T, U, V, W, X, and Y have no convincing numerical equivalent.

4. Does this work on modern calculators or phone apps?

Often, no. Many modern calculators and phone apps use dot-matrix or high-resolution displays that show numbers too perfectly. The trick relies on the blocky, stylized look of old 7-segment displays. This calculator helps you find things to write with a calculator, even if you don’t have the old hardware.

5. What are the longest things to write with a calculator?

Words with 11 or 12 letters are considered very long. Examples include “SLEIGHBELLS” and “HILLBILLIES”. Finding such long, valid words is a significant challenge.

6. Where did the term “beghilos” come from?

It’s a mnemonic that includes the core letters available for calculator spelling: B, E, G, H, I, L, O, S. Sometimes ‘Z’ is added to make “beghilosz”. It’s a handy way to remember the limited alphabet for things to write with a calculator.

7. Can I use this for my date calculator?

While you can spell some words, dates themselves are not easily convertible into meaningful words using this method. This tool is more for novelty and fun than for practical date calculations.

8. Are there any numbers that spell words right-side up?

Yes, though it’s much rarer. For example, on some displays, ‘8008’ can look like ‘BOOB’ both right-side up and upside down. Another example is using hexadecimal on scientific calculators.
