BEGHILOS (or BEGHILOSZ or Calculator Spelling) is a writing method based on the use of a calculator read backwards.
This method is limited to hardware using 7-segment displays to represent digits/numbers.
With calculator spelling, each letter is associated to a digit, it is a substitution, limited to characters BEGHILOSZ corresponding to 9 digits respectively 836417052.
The message is then written backward (to be read, with a 180° rotation).
Decryption is made with an upside down reading (180° degrees) or a replacement of the digits with the letters 8 3 6 4 1 7 0 5 2 = B E G H I L O S Z then a backward writing.
Example: 376006 => ELGOOG => GOOGLE
The message has mainly 3, 1, 5 and 0 characters.
The numbers or letters should be similar to a 7-segment display.
Calculator writing is sometimes used as a learning tool for children who can become familiar with numbers and letters while having fun creating words in BEGHILOS.
Only words with BEGHILOSZ letters are correctly working. Use the longest word solver to find all possible words such as: BOBSLEIGH, ELIGIBLE, BIOLOGIES etc.
BEGHILOS must be used on calculators equipped with a 7-segment display. Calculators with more modern displays will generally not be suitable.
