How to Write Words With a Calculator

Students have been spelling words on calculators in math class for decades. Luckily, that means there are long lists of words you can spell on a calculator and the numbers you need to make them. Older calculators work better for this trick, so ask your parents if they still have their school calculators lying around somewhere. See how many words you can spell!

Using the Hexadecimal Mode

1
Switch your calculator to hexadecimal mode. Not all calculators have a hexadecimal mode, but if yours does, you will have more letters to spell words with. You will be able to tell if your calculator has a hexadecimal mode if you see the letters A-F on the keyboard.^{[1]XResearch source}
- Calculators that have hexadecimal mode include Casios and Texas Instruments.
2
Use a combination of letters and numbers to spell words. In hexadecimal mode, you will have the letters A, B, C, D, E, and F. You can also use the numbers 1 for I, 0 for O, and 5 for S.^{[2]XResearch source}
- For example, you can spell the word "see" using 5EE.
- Some other words you can spell include BASS, DIE, BOSS, DOE, and SEA.

Create even more combinations by turning your calculator upside down. When you turn your calculator upside down in hexadecimal mode, you can turn b into q and d into p. Along with q and p, you can make the letters O, D, I, Z, E, h, A, S, g/q, L, B, and G from numbers. The possibilities are endless!
- b=q
- d=p
- 0=O/D
- 1=I
- 2=Z
- 3=E
- 4=h/A
- 5=S
- 6=g/q
- 7=L
- 8=B
- 9=G/b
- You can also use the number 2 instead of the word "to" or "too."

Use specific numbers to represent different letters. Each number looks like a different letter when you turn it upside down. You can use those letters to write lots of words. Here is a list of letters you can use:^{[3]XResearch source}
- 0=O/D
- 1=I
- 2=Z
- 3=E
- 4=h/A
- 5=S
- 6=g/q
- 7=L/t
- 8=B
- 9=G/b
2
Write a word on a piece of paper. To see if you will be able to spell the word, check your list to see if all of the letters match up with a number. If a letter you want to use isn't on the list, you won't be able to spell the word.^{[4]XResearch source}
- "HELLO" is a classic word to spell on a calculator. Notice that all of the letters are on the list.
- Some other words that you can spell on a calculator are IGLOOS, GIGGLE, SHOES, and EGG. Look at the list of letters and see what words you can spell with them.
3
Write down the number that matches up with each letter. Write the number that matches it on the list underneath each letter. These are the numbers you will use to spell your word. Each letter should have one number.^{[5]XResearch source}
- To spell "HELLO," the matching numbers are 43770.
4
Type the numbers you wrote down backward into your calculator. Start with the last letter of the word. When you turn your calculator upside down, the order of the letters will be backward—that is, in the right order to spell your word!^{[6]XResearch source}
- For example, to spell "HELLO," you will reverse the numbers so that they read 0.7734.
- If the word ends with an "o," start with 0 then add a decimal (.) so that when you press "enter" or "=" the 0 will still be there.
Press enter and turn your calculator upside down. Some calculators have an "enter" button and some calculators only have an = button. Press whichever one your calculator has. Flip your calculator around so that the top of your calculator is closest to you. Your word will appear!^{[7]XResearch source}

Writing swear words or negative messages to friends as a prank may seem funny, but should be avoided since it risks harming your relationships or getting in trouble. Consider more positive uses for spelled words.
If your calculator has secondary functions, look for buttons labeled things like "DRG" or "2nd" to access additional features. The manual can explain special shortcuts you may not notice at first.
Be extremely cautious about downloading any app, game or program to your calculator, especially from an untrusted source. These could contain viruses or malware designed to hack your device.
Many calculators have "alpha" buttons that enable entering letters directly instead of writing words upside-down. Refer to your model's manual or explore the buttons to unlock letter keys.
When bored in class, resist the temptation to play around on your calculator too obviously. Teachers can still notice the button clicks. Stay focused as best you can on the material.
