What's a little disturbing about the above archive is that all the files are dated "Dec 24 1996". However, if you dig around a bit more on the Internet Archive, you discover that A Large Collection of DOS Collections contains:

• DOS Collection v0.7/DVD1/Adventures In Math (1983)(Ibm).zip
• main torrent/1983/Adventures in Math (1983)(IBM) [Educational].zip

In the first ZIP file:

-rw-r--r--@ 1 Jeff  staff    170 Jan 22  2011 file_id.diz

So we're going to start with the second ZIP file. One oddity common to all these archives is the file "MONOCODE.000". Dumping that file reveals:

00000c60  20 4d 4f 4e 4f 50 4f 4c  59 20 69 73 20 61 20 72  | MONOPOLY is a r|

so it seems pretty clear that whoever created this disk had copied other unrelated (eg, MONOPOLY) game files to it, and if/when someone tried to clean it up later, they missed this file. I've deleted it.

Another oddity is "BASICA.EXE" (54277 bytes) from 1999. It seems unlikely that IBM would have distributed any BASIC binary with this game, because DOS was a prerequisite, and all versions of DOS included BASIC. IBM's PC-DOS shipped with "BASICA.COM", and OEM versions of DOS shipped with either "GWBASIC.EXE" or "BASIC.EXE".

The closest binary I'd seen up to this point was "BASICA.EXE" from COMPAQ DOS 1.12 (54304 bytes). And sure enough, this "BASICA.EXE" is a close relative, since it contains the strings:

The COMPAQ Personal Computer BASIC
Version 1.13
(C) Copyright COMPAQ Computer Corp. 1983

It's unlikely that IBM would have distributed a COMPAQ binary; if they had distributed any BASIC binary with this game at all, it would have been their own "BASICA.COM", and since that binary also requires IBM's ROM BASIC, a more generic BASIC binary was desirable.

I've deleted "BASICA.EXE". The proper thing to do -- and what any purchaser of this game would have to do -- is boot a machine with a disk containing some version of BASIC and use that.

Finally, there was "FILE_ID.DIZ":

Adventures in Math (1983)(IBM) [Educational].zip

and "RUN.BAT":

Those files have been deleted as well, leaving 8 files dated "Aug 11 1983". I created a disk image from the directory containing those files:
