This can not be used for faster than light communication. No "information" is exchanged in the "teleportation" it is just that one can "copy" a quantum mechanical state from one place to another, which of course is crucial for building quantum computers. For more explanation on the difference between entangelment and FTL communication see for example see a discussion of the EPR Paradox.
Both in English and Hebrew when you utter 531 out loud, you first say the hundreds, then the tens and finally the ones. So when I think of the number (five hundred and thrity one) and want to type it in, it is more natural to type the 5 first. Are there any languages where the one's digit is uttered first? I know that there are several places in the bible where it is done that way (E.g. When the matriarch Sarah passes away her age is stated as "seven and twenty and one hundred years") but even there it is unusual.
Doing Bi-directional text well has lots of pitfalls. E.g. the software has to recognize when you start typing in a number and switch directions (The number five hundred thirty one still appears as 531 in hebrew, not 135).
Mixing left-to-right with right-to-left is even worse. E.g. when you are on the boundary between the two texts and hit the backspace key, which piece of text gets erased?
Lots of other subtle problems to getting it perfect. I hope they did a good job.
Surreal Numbers by Conway. Not exactly what the original question asked. Here is an excellent text which shows how math is actually done. I.e. how proofs come into existence. More correctly, ONE of the ways how math is done. This is a delightful short book, written in story form. Not only is the subject very interesting, the insight into how math is done is lovely. I highly recommend this. WARNING: Reading the book requires a certain level of mathematical sophistication. Definitely NOT a light read.
