My condolences go out to your parents.
Cooper Richardson
Sounds like your teachers are just douches who like throwing you into the deep end. I learned all of that over a period of weeks. Proofing De Morgan's Law shouldn't be difficult if your teacher has gone over other examples.
Nicholas Morris
>Proofing De Morgan's Law shouldn't be difficult if your teacher has gone over other examples Yeah I wish there was a quick rundown like Noam Nisan's course. I only learned after the fact all of the formal names for what I was doing.

The handwriting makes me think it's just a kid. Teacher is right tho, 5x3 is not equivalent to 5+5+5.
William Gomez
Is 5x3 not just three 5s?
Logan Murphy
5x3 is not 3x5. They equal the same, but are not equivalent. 5x3 is like 5 bundles of 3 apples each. You have 15 apples. But 5 bundles of 3 is very different than 3 bundles of 5.
Justin Gomez
The commutative property would like to have a word with you. Abstract mathematics not practical applications.
Nathaniel White
Saying 5+5+5 is incorrect You do not have 3 sets of 5, you have 5 sets of 3. They are equal, but not equivalent. Perhaps you don't know what the word equivalent means?
It would matter in many situations, especially if you had variables. Think of it as bundles * apples. If bundles cost $2, and you have 5 bundles of 3 apples, you have $10 worth of product.
Increasing the number of bundles you have to 6 means you have $12 worth of product.
But increasing the number of apples in the bundles to 4 does not change the fact each bundle is set to $2.
Luis Phillips
was it on the syllabus?
the kid is right. the teacher's brain works backwards

>Week 1 >You will be learning about simple low-level computer architectures that make up processing units. >At the end of the week you will be able to design simple schematics for powerful Arithmetic Logical Units
Ryan Anderson
>Arithmetic Logical Units that's your key phrase
Samuel Ramirez
Numbers are abstract concepts of value. There is no bundles * apples, like there is in statistics or applied maths, only numbers. 5x3 is 15 apples, you can also say there are 3x5 apples which is also 15. This is the commutative property of multiplication. If the original question said bundles * apples, you would be correct, but it says only numbers, nothing more.

Perhaps my preconceptions about the class were wrong. I assumed I was going to be introduced to the topic, not dropped into a gladiator pit with it. >DDG Checkout Searx on github if you're big on privacy.
Chase Collins
either one works. when i see 5x3 my mind says their are 3 5s. Teacher was just being a cunt. I'm guessing she has little else to do other than micromanage some kids' time tables.
Xavier Collins
>dropped into a gladiator pit but did you die? I assume he's not actually going to end up dropping everyone? or maybe he's just sink or swim? >Checkout Searx on github if you're big on privacy. will do.
Kayden Martinez
>I assume he's not actually going to end up dropping everyone? or maybe he's just sink or swim? The class'll find out soon enough. >but did you die? A part of my innocence was lost today.
Andrew Lee
that's pedantic bullshit that hinders more than it helps
Colton Ross
you were taught this bullshit in school, weren't you? that's why you're retarded.
Isaac Richardson
Why are you taking such a course without knowing the basics of formal logic?
Tyler Peterson
If this is your first semester it is designed to make you drop out, at least here in Germany that is the case.
If it isn't why don't you know about Boolean logic?
