In TSL, numbers one to four can be signed either horizontally or vertically. Horizontal signs indicate ordinal numbers, with the sign dangling a bit or held to the side. E.g. first (point, item, section), second (point, item, section), third (point, item, section). Vertical signs indicate cardinal numbers, such as code, amount of money, and age. If you wish to see examples, please refer to video samples of sentences containing numbers. However, numbers six to nine are always horizontal, whether cardinal or ordinal.
