LaTeXでは空白を意味するコマンドが用意されている。空白は「+半角空白」をよく使うが、quadやhspaceもある。
| quad | 1 字分 |
| qquad | 2 字分 |
| \, | quad の 3/18 倍 |
| \: | quad の 4/18 倍 |
| \; | quad の 5/18 倍 |
| \! | quad の -3/18 倍 |

ポイント
- xyもx yも同じで、単にスペースを空けても反映されない
- 半角スペースは「+半角スペース」
- 全角スペースはquad
!は負のスペースで、記号と記号の間をデフォルトより短くしたいときに使う。hspaceはカッコ内の値によってスペースの長さを調節できる（表の下）。
