Actually I'm surprised that any school *wouldn't* teach binary-octal-hex conversions. Converting to base 10 can be somewhat cumbersome on paper, but going from binary to octal or hex is a snap. I usually use my HP-16C for that sort of thing, but sometimes it's quicker to do it without the calculator., My 7th grade math class included binary to decimal conversions and binary math in 1967, at a time when most students might have expected never to see a computer anywhere but on TV.

It was fun student instructing the course and seeing those kids struggle without their calculators. I had one kid who could program his TI-85 to do the conversions but could not do it by hand. Most mistakes were in addition and subtraction, 119 + 13 = 122 instead of 132. -----Original Message----- From: HP-3000 Systems Discussion [mailto:[log in to unmask]]On Behalf Of Doug Becker Sent: Wednesday, September 13, 2000 11:52 AM To: [log in to unmask] Subject: Re: communication skills (was: new look & feel forjazz) Tracy Johnson wrote: "I was just mentioning to someone this evening how effective a torture technique it is (and how valuable it would be to High School students) to force feed the manual methods to convert Binary to Octal to Hexadecimal and back again, in their basic computer course." I remember the days the RCA Software Engineer came in with a hand held LED calculator that would change between the different bases. I wanted one of those *SO BAD* I could taste it--debugging EBCDIC dumps from RCA DOS would have been wondrous. Unfortunately, they were $600 at the time.
