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!

Method 1 of 2:

Using the Hexadecimal Mode

  1. 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]
    • Calculators that have hexadecimal mode include Casios and Texas Instruments.
  2. 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]
    • For example, you can spell the word "see" using 5EE.
    • Some other words you can spell include BASS, DIE, BOSS, DOE, and SEA.

  3. 3
    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."

Method 2 of 2:

Turning Your Calculator Upside Down

  1. 1
    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]
    • 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. 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]
    • "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. 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]
    • To spell "HELLO," the matching numbers are 43770.
  4. 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]
    • 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.
  5. 5
    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]
  6. 6
    Try spelling some examples. To take the guess work out of whether or not you can spell a certain word, look for a list of words that have already been figured out. Here are a few examples[8] :
    • 376006 spells GOOGLE
    • 707 spells LOL
    • 0.08 spells BOO
    • 53177187714 spells HILLBILLIES
    • 500761 spells IGLOOS
    • 38 spells BE, 338 spells BEE

    • 0.208 spells BOZO
    • 663 spells EGG
    • 336 spells GEE
    • 376616 spells GIGGLE
    • 378806 spells GOBBLE
    • 637 spells LEG

Article SummaryX

If you want to write words with a calculator, start by memorizing what numbers look like which letters when the calculator is held upside down. For example, 3's look like E's and 7's look like L's. Once you know what word you want to type, enter the numbers backward and then hold the calculator upside down to see the word. For example, type 379009 in your calculator to spell out GOOGLE. Or, try typing 5317 to spell out LIES. To learn how to type out more words, like "SORRY" and "LOL," scroll down!
