Or and Not Both

arabprodigy30 · February 2015

Hey guys, just need you to verify of this is correct from my understanding.....

You must buy milk or eggs or both

Diagram :

Not M ->E
Not E->M ? (So implies either M or E, you can get both)

You can't buy both milk and eggs

Diagram:

E-> not M
M-> not E ? (So implies either E or M , or NEITHER?...you do not even need to buy both?)

That's correct, @SoltanShah! You're also right that, in the second statement, you can buy nothing.

Keep it up!

Yes

You can have either Soup or Salad
Means you can have 1 or both

You can have Soup or Salad but not both
Means 1 must be absent

Good job

Btw, there's also a PDF with "or" and "not both" rules. It should be towards the end in one of those lessons.

@SoltanShah, you're definitely going about this the right way! The better you know your fundamentals, the better you'll be able to handle the curve breakers.

@emli1000 ah thank you! I think I skipped over the pdf i need to go back and print it out!
@allisonM thank you, I don't know where would I be without sage! I did not even know these fundamentals (and I took a prep course) ! but with Sage I learned so much ! I will tell all my friends about this

Howdy, Stranger!
