Whats the theory behind this?

[FFactory0x]

My friend is taking a course where they teach you that 1+1 does not equal 2. This like that. Whats the point behind it

Logic. In logic, 1+1 = 1

Yes your friend is taking a course in logic

Well where the hell is the logic behind 1+1=1
So stupid

Uhh, ever hear of Boolean Algebra? Or binary 'OR' for two values of 1?

 

[So]

1 + 1 = Pi*e*(pi^2 - e^2)/[(.5 Pi^2 + .5 Pi*e)(.5 Pi*e - .5e^2)]

 

[Tommunist]

only 2 values: 1 and 0
a few diff operators on of which is + otherwise known as "or"

0 + 0 = 0
0 + 1 = 1
1 + 0 = 1
1 + 1 = 1

true + true = true

1 = true

So stupid. So basically they are teaching you something that goes against everything they have ever taught you in school. Basically if i had a test in another subject and added wrong like 1+1=2 and they checked it as a wrong answer. I could argue that its correct

i.e. NOT false.

No, no, no.

The '+' operator is a logical OR, not addition in the common sense.

edit: 1+1 in binary = 10

how do you have over 5k posts in a computer based forum and know nothing of boolean algebra???

lol thats what i was wondering

j/k.

i took a logic course my sophomore year in college, and at first, seeing 1 + 1 = 1 was kind of wierd. but you quickly get used to the boolean math as well as the other operators too.

but unless you said it was a logical math class, then yea, 1+1 = 1 doesn't look right. but if you had said it was a discrete math class, then it would have made sense.

Not if "+" doesn't mean what you're accustomed to it meaning. God forbid you learn something new and expand the way you think a bit. To be fair, though, I've never been a big fan of using "+" for OR.

FFactory0x ... so now tell us.

what does 1 - 1 equal in this new math class ...

Why do I get the feeling that this is a parody thread? I'm not on the forums enough to know nowadays.

They're not. '+' is no longer an addition operator. In your OP, '1+1=1' is saying '1 or 1 is 1' which is 'true or true is true' which is a true statement.

1+1 = 2 is saying '1 added to 1 sums to 2.' This is also a true statement. All they did was switch the meaning of the operator. It's really very simple. Changing the operator doesn't mean anything at all, 'sum' and 'or' still retain their respective meanings.

whenever someone asks what 1+1 is and you respond with "actually...", be prepared to get smacked in the head... hard.
