実質20進法の演算表です。日常の10進数法以外の基数による数字の表記を教えるとき、「アラビア数字以外の表記があったらなぁ」と思ってたので作りました。
マヤ文明で使われていた文字(数字)らしいです。20までの数字があり、それより大きい数字は位取り記法で書いていたとか。大きい位は上に書かれるみたいです。
通常の数字との対応表は次の通り。
| アラビア数字 | マヤ数字 |
|---|---|
| 0 | 𝋠 |
| 1 | 𝋡 |
| 2 | 𝋢 |
| 3 | 𝋣 |
| 4 | 𝋤 |
| 5 | 𝋥 |
| 6 | 𝋦 |
| 7 | 𝋧 |
| 8 | 𝋨 |
| 9 | 𝋩 |
| 10 | 𝋪 |
| 11 | 𝋫 |
| 12 | 𝋬 |
| 13 | 𝋭 |
| 14 | 𝋮 |
| 15 | 𝋯 |
| 16 | 𝋰 |
| 17 | 𝋱 |
| 18 | 𝋲 |
| 19 | 𝋳 |
𝋠 は 0 ではなく 20 という話もあるとか。
