Proving 0.999 is equal to 1
- frobozz 16y agoIt isn't, 0.999... is, but 0.999 is exactly 0.001 less than 1.
- dansingerman 16y agoI can remember arguing in middle school (I was 9) with my teacher that 0.999' was equal to 1. Sadly, at the time. despite knowing this as a fact, I didn't know any of the proofs. Mind, I don't think they would have convinced her.
- tychonoff 16y agoWithout reference to the formal notion of limits in real numbers (invented in the 19th century), the expression 1=0.999... is meaningless. So one shouldn't be surprised at the confusion and dumb arguments surrounding it.
- bd808 16y agoA friend showed me this "proof" that makes it easier to explain to people who aren't math nerds. 1/3 + 1/3 + 1/3 = 3/3 = 1 .3¯3 + .3¯3 + .3¯3 = .9¯9 = 1
