During one week, Machine B worked five more hours than Machine A but produced the same number of widgets as Machine A. How many hours did Machine A work that week?
4. ## 1 + 2 = 4?

I correct you. You're wrong. 1 + 2 = 3 is not "technically a lie."
5. ## 1 + 2 = 4?

i'm not fully sure what you are asking, yes, no object is perfectly identical to another, but that doesn't mean they are necessarily worth less/more. if i have two apples, one shaped like a pear, the other like a cucumber, i still have two apples.

Thanks, about what I guessed. I just didn't take the time to follow it to its full conclusion

10. ## Just an old (Tennessee) mountain goat.

I've been playing around with puzzle geocaches for awhile, now, on a fb page dedicated to them. Someone asked for help on one that was a logic problem. HEAVEN!!!! Another poster said it sounded like Einstein's riddle, which I'd never heard of. So of course I googled it, and solved it in less than an hour. But one of the listings that came up in the google search was BrainDen. Two puzzles later, I'm hooked. So, what are the reputation points all about?

flamebirde, sorry to have spoiled your fun. I'm new to this site, and didn't notice I had to hit the eye in order to hide my answer. Please forgive a newbie.

22. ## 1 + 2 = 4?

| absolute value signs missing - it's all relative.
23. ## 1 + 2 = 4?

when comparing apples to bananas . we only know |1| + |2| = |3| absolutely. 1 + 2 = 3 is technically a lie. So what I'm asking, is the answer 4? 1 + 2 = 4 > 1 + 2 = 3 correct me if im wrong. nothing is whole, pure, not rotten, or the same size. We are taught to lie in school. argumentative papers taking quotes out of context to prove a false point right. Should we not be selling 3 as 4? - supersaturated ..
