#1-6  Logic of AND, OR// TEACHING TRUE MATHEMATICS, 2018, by Archimedes Plutonium 

Now, today in this lesson we do Logic. We start Logic, we start a new topic, which is a relief to some 8 year olds who spent the last 3 or 4 months learning decimals. Ask the students if they ever watched Star Trek and Dr. Spock. Well, logic is what Dr. Spock was proud of, and it was his specialty. Even though it was science fiction, we see what logic is about-- thinking cool, thinking straight, thinking clear, thinking correctly.

Now there are two types of Logic, one is called Algebra Logic and the other is called Geometry Logic. We will hear and see more about Geometry Logic later on, but for now we do Algebraic Logic. Ask the class if anyone knows what "Algebra" means. Well, Algebra means analysis of parts of a whole. Algebra means we  look at and examine parts of a whole. To examine and inspect parts of a whole. In this case-- to examine and inspect grammar and words as parts of a whole sentence in Language. Here are two sentences. 

(1) The Earth goes around the Sun and the Moon goes around Earth. 

(2) Either the refrigerator is working because it is plugged into the electric outlet, or, the refrigerator is not working because it is not plugged in to the electric outlet. 

And today we learn two connectors of Algebraic Logic, the AND, and the OR. Do you see those two sentences of Language and do you see the "and" in sentence (1)? Do you see the "either,, or" in sentence (2) ? 

So, teacher, do about a page full of AND statements and a page full of OR statements. 

Something like this: 

The boy with the ball and the girl with the bat went to the backyard field to play. 

That can be broken down into 

The boy with the ball went to the backyard field to play. 

The girl with the bat went to the backyard field to play. 

So we stick an AND in those two sentences to produce our original sentence. Ask the class what is And like? Is it like add, like subtract, like multiply, like divide? 

A OR example. 

Either it rains at noon time today or it is sunshine at noon today. 

So, ask the class what that OR is like, is it add, subtract, multiply, divide? 

Show them it is subtract, for at Noon time, if it is raining it is not sunny and you subtracted sunshine. But if it is sunny, it is not raining and so you subtracted out the rain. 

Now many examples come from math itself. 

2 AND 3 is what? It is 5 

7 OR 10 is what? Well if you have 7 not 10 you subtracted 10, and if you have 10 not 7 you subtracted 7. OR is one of two items but never both. OR is subtraction. 

AND is the joining together of items. AND is add, OR is subtract, remove. 

So have a sheet full of AND examples and another sheet full of OR examples. 

Warning to Teacher: please spend considerable time on composing AND, OR statements, especially OR statements, for although we may think this is easy material, in fact, it is difficult to do nice pure logical statements. So prepare the night before especially well and cautiously. 

So go over the above exercises with about several days of new examples of AND and of OR.  I want to go over again AND of Logic and OR of Logic. Here again, give the students a whole page of AND statements. Another whole page of OR statements and let them figure out how the AND is adding, and then, how the OR is subtracting by choosing one item and dismissing the other item. 

Summary:: We learned what Algebra means-- a examination of parts of a whole and we learned Algebra Logic is the examination of sentences and words of Language, a look at grammar of language and words in sentences. 

You be surprised at how well students at this young age of 8 years, pickup on knowledge. When I was a teacher, my favorite classes were these young students for their sole interest in life at that age was learning. A little older and then body hormones kick in and the students are interested in other things also and easily distracted. 

So the lessons on Decimals took about 4 months. The lessons on Logic, And with Or, is only going to take a week or two, not much.

I re-opened the old newsgroup PAU of 1990s and there one can read my recent posts without the hassle of spammers, off-topic-misfits, front-page-hogs, stalking mockers, suppression-bullies, and demonizers.      

Read my recent posts in peace and quiet.

You need to quit failing...it is so annoying...
