## Korea has two different number systems. One is used mainly for counting and age, the other is used everywhere else.

In Korean, the first number system is the native korean system, which is mainly used to count things, to say your age, and to say the hour of the time. They are:

하나(1), 둘(2), 셋(3), 넷(4), 다섯(5), 여섯(6), 일곱(7), 여덟(8), 아홉(9), 열(10), 스물(20), 서른(30)

Note that in usage, 하나 -> 한, 둘 -> 두, 셋 -> 세, 넷 -> 네, 스물 -> 스무.

The second system is the Sino-Korean system, and it is used in every other situation from math to money. They are:

영(0), 일(1), 이(2), 삼(3), 사(4), 오(5), 육(6), 칠(7), 팔(8), 구(9), 십(10), 백(100), 천(1000), 만(10000), 억(100000000)

To say any number, just combine the numbers together.
For example, 25 is 이(2) + 십(10) + 오(5) = 이십오(25).
In the other system, it’s 스물(20) + 다섯(5) = 스물다섯(25).

The year 1999 is thus 천(1000)+구백(900)+구십(90)+구(9) = 천구백구십구년 (Year 1999)

Examples

저는 스물두 살이에요 = I am twenty two years old.

맥주 병 주세요! = I’ll have three bottles of beer please!

저는 이십 불 있어요 = I have twenty dollars.

삼십만원 있어요 = I have 300,000 Won.

I loveeee gadgets (See here). Especially gadgets which have to do with simulating reality, virtual reality, and augmented reality. And here’s the top 5 list of the VR/AR gadgets that I’m most excited about in the near future.

1. Oculus Rift

Man, this thing sounds really cool. I know developer editions are already shipping, but I can’t wait for the consumer versions to come out. I mean, being able to play games and have head tracking and that immersive feel is just awesome, and something I’ve been wanting to do for a long time. Imagine playing Fallout 3 and feeling you are actually inside that nuclear wasteland. So cool.

2. Meta glasses

The developer says that this is Google glasses on steroids. Basically its a more powerful, more featured version of Google glass, so you can imagine what thats like. In the video they had all sorts of augmented reality showcases, and it looks really cool and fun. They are currently shipping developer editions early next year, so I hope that it does what they say it will do. And I know Vuzix already has production versions of its augmented reality glasses, but this is much more affordable.

3. Sixense STEM system and ControlVR system

These two devices are basically augment the virtual reality experience of the Oculus Rift/Sony HMZ/PS4 VR when playing games, specifically using the hands and arms. The STEM system puts sensor pads over some analogy controllers and packs so that individual limbs can be tracked, and ControlVR looks like a Kinect or Leap-motion-esque controller which has no physical device, unlike the STEM. By the way, the developer Sixense also made the Razer Hydra, so you know they have street cred.
