Read a file and save every word in a variable to use

Hello there

so i have a txt file containing word like "one two three four plus four five six".

I want to save every word in the file into a variable, and then use that variable to generate real numbers and apply the arithmetic value on them.

example: the txt files becomes 123 + 456 and give the result.

I got the idea to use this:
Code:
for word in $(<$file); do
                #echo "$word"
done
this only read every word. I tried to do:
case "$word" in
                   "zero") $word = "0"

and so on but it doesn't actually allow me to save each word in a different variable.

Thanks in advance

WORD-LIST-COMPRESS(1)					 Aspell Abbreviated User's Manual				     WORD-LIST-COMPRESS(1)

NAME
word-list-compress - word list compressor/decompressor for GNU Aspell SYNOPSIS
word-list-compress c[ompress] | d[ecompress] DESCRIPTION
word-list-compress compresses or decompresses sorted word lists for use with the GNU Aspell spell checker. COMMANDS
-c, c, compress compress the plain text word list read from standard input. -d, d, decompress decompress the compressed word list read from standard input. EXAMPLES
Here are a few examples of how you can use word-list-compress word-list-compress d <wordlist.cwl >wordlist.txt Decompress file wordlist.cwl to text file wordlist.txt word-list-compress c <wordlist.wl >wordlist.cwl 2>errors.txt Compress wordlist.wl to wordlist.cwl and send any error messages to a text file named errors.txt LC_COLLATE=C sort -u <wordlist.txt | word-list-compress c >wordlist.cwl Sort a word list, then pipe it to word-list-compress to create a compressed binary wordlist.cwl file. word-list-compress d <words.cwl | aspell create master ./words.rws Decompress a wordlist, then pipe it to aspell(1) to create a spelling list. Please check the aspell(1) info manual for proper usage and options. TIPS
Word-list-compress is best used with sorted word list type files. It is not a general purpose compression program since the resulting files may actually increase in size. Word-list-compress accepts up to 255 text characters in the range of {0x21...0xFF}. If your word list requires a larger character set for certain languages or longer length for multi-word, scientific, medical, technical or other use, then it is recommended that you compress your word list using prezip-bin(1) DIAGNOSTICS
Word-list-compress normally exits with a return code of 0. If it encounters an error, a message is sent to standard error output (stderr), and word-list-compress exits with a non-zero return value. Error messages are listed below: (display help/usage message) Unknown command given on the command line so word-list-compress displays a usage message to standard error output. Corrupt Input This is only for the decompression command d. The input file is of an unknown format or the input file/stream is corrupted. You may have some valid output, but word-list-compress could not complete the process. If the input file is a compressed wordlist but you have no output file, then it may be a newer prezip-bin(1) version of compressed file, if so, try decompressing the file with prezip-bin(1) instead. Output Data Error The output is full, write protected, or has an error and can no longer be written to. SEE ALSO
aspell(1), aspell-import(1), prezip-bin(1), run-with-aspell(1) Aspell is fully documented in its Texinfo manual. See the `aspell' entry in info for more complete documentation. REPORTING BUGS
