That's just gross.

Boolean algebra is probably the easiest for people to grasp, as you can use real world examples:

ENDIFBinary and HEX (or any other base) are especially challenging for people whose mathematical abilies may not be very high. I tried to explain both of those to someone once but they just could not get it.

If your goal is to get the following three concepts into the minds of a large group of people... 1. Binary Arithmetic 2. Boolean Algebra 3. Hexadecimal Arithmetic ...In what order would you present the concepts ? (That list is in alphabetical order to prevent any implied bias) Why do you feel that your chosen sequence makes more sense than others ?
You have to provide adequate incentive, threaten grievous bodily harm to those who don't understand maybe? :laugh:

You'd have more luck getting them to recite that rhyme straight ten times. On a slightly more serious note, hex is just binary, 4 bits at a time. Maybe mention octal as a stepping stone.

I doubt that is useful. "Number theory", at best, covers quite a bit more than what was actually asked for. So attempting to answer the original question with that is not a good idea.

First make everyone drink two coffees and a bottle of water and then tell them there are no breaks. That will keep questions to a minimum! My top of the head approach: Boolean Algebra with true and false then teach false is 0 true is 1 Repeat Boolean Algebra module now with 0/1 Then introduce using groups of two bits repeat Boolean Algebra with two bits. Show 4, then 8, 16, 32 quickly. do a few exercises with 8 bits. (Optional: at this time XOR) Now introduce some other binary operators like addition and subtraction, then two’s complement and “signed” values in binary. (optional: Overflow exceptions and how to calculate overflow. or only cover this if someone brings it up. still have some content prepared on the topic) Now that you are starting to treat blocks of bits as numbers, hammer home place value in binary (as well as review same in decimal system) Show how in decimal we bundle by groups of three digits: ones, thousands, millions. Then segue from there on how to bundle 4bits into a nibble, and then show hexadecimal. (Separate the classroom then on people who think hexadecimal should use upper case or lower case for A-F for no reason just to mix things up) show hexadecimal place value, do a few simple additions and subtractions in hex.

You could create the presentation as an article to solicit feedback. And then dismiss poor reviews of your presentation thusly “Wow, I found this as an article on codeproject.com, I thought they knew their stuff! Sorry.” Might need to scrub your bio if you execute this suggestion!

I wasn’t suggesting you learn it Richard I’m sure you know it better than most

I would start with Boolean Algebra, just to introduce the student to the many useful things a number system with only two possible digits can be. Then I would extend the concepts to binary arithmetic, to demonstrate the interchangeability of number systems, given the proper conversions. Lastly I would introduce the hexadecimal notation, with emphasis on the usefulness of this shorthand way to represent what is, essentially, a binary representation. In practice, I actually started down the logic road in grade school, learning about sets, and expressing relationships with Venn Diagrams. Later came the transition to general logic, binary, then octal, then hexadecimal arithmetic, and state transition diagrams.

I'd just flip 2 with 3 So 1,3 then 2 Mostly because binary and base 16 arithmetic are best made mentally (and hexadecimal can be broken down to binary easily in case of brain fart) Boolean Algebra is a whole world by itself and because the choice of 1 and 0 for True and False is totally arbitrary, it doesn't necessarily follow the former two. People eventually memorize the basic tables of AND, OR and XOR by way of assembling digital circuits (the fun part)
